Jikes 1.15 is completely broken, jikes 1.15b fixes some of the errors but leaves in at least one major one: VerifyErrors on any constructor of a non-static inner class that is either non-public or calls this(). I've also heard bad things about jikes 1.14, but didn't hit any of those personally. I recommend requiring specifically jikes 1.13 until 1.16 comes out.

[Jikes] IBM releases Jikes Research Virtual Machine on developerworks(fwd)
FYI- -Archie From [EMAIL PROTECTED] Mon Oct 15 09:20:01 2001 From: David Shields [EMAIL PROTECTED] Subject: [Jikes] IBM releases Jikes Research Virtual Machine on developerworks Date: Mon, 15 Oct 2001 11:46:15 -0400 Just to let you know that IBM Research has just released the Jikes Research Virtual Machine (RVM) on developerworks: http://oss.software.ibm.com/developerworks/projects/jikesrvm The RVM is designed to execute Java programs that are typically used in research on fundamental virtual machine design issues. It will provide academic and research communities with a flexible testbed to prototype new virtual machine technologies and experiment with different design alternatives. It runs on the AIX/PowerPC, Linux/PowerPC, and Linux/IA-32 platforms, and exhibits industry-strength performance for many benchmark programs on the first two of these platforms. The Jikes RVM includes the latest VM technologies for dynamic compilation, adaptive optimization, garbage collection, thread scheduling, and synchronization. The Jikes RVM is implemented in the Java programming language. It was originally hoped to release the project using the name Jalapeno that was internally used during its development. However, it turns out some company has a claim on this name, so we decided to use Jikes, as we have done before for projects from the Software Technology department here at IBM Research. The project has no direct link to the Jikes Compiler Project other than requiring the Jikes compiler for its compilation. Indeed, this is the reason Jikes supports the the +K option. dave __ Archie Cobbs * Packet Design * http://www.packetdesign.com

Announcing new version of LaTTe JVM and JIT Compiler (fwd)
FYI- -Archie - Forwarded message from Prof. Soo-Mook Moon - From [EMAIL PROTECTED] Wed Oct 25 06:48:40 2000 Date: Wed, 25 Oct 2000 20:20:53 +0900 (KST) From: "Prof. Soo-Mook Moon" [EMAIL PROTECTED] Message-Id: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Announcing new version of LaTTe JVM and JIT Compiler Content-Length: 3369 My apologies if you receive multiple copies... = Subject: Announcing new release of LaTTe open-source Java Virtual Machine, with performance improvements Version 0.9.1 of the LaTTe virtual machine has been released. LaTTe is a freely available virtual machine intended to execute Java classes. It can be obtained from http://latte.snu.ac.kr/. LaTTe is research prototype for the study of dynamic (just-in-time) compilation techniques. Among its features are: * A fast and effective JIT compiler with - efficient register mapping and allocation - "traditional" optimizations (e.g., common subexpression elimination) - object-oriented optimizations (e.g., customization and specialization) * A limited framework for adaptive compilation, which is currently based on method run counts. * A reasonably fast bytecode interpreter, intended to be used with the adaptive compilation framework. * Lightweight monitors. * On-demand translation of exception handlers. * A fast, non-incremental garbage collector. As a result, the performance of the LaTTe JVM is competitive with that of commercial JVMs, such as Sun's JDK 1.2 production release and JDK 1.3 release candidate client/server VMs. Changes from version 0.9.0 include: * Addition of new optimizations such as faster class inclusion tests, LOOKUPSWITCH optimization, de-virtualization of method invocations, and the use of native 64 bit instructions. These result in a 10% performance improvement in our benchmarks. * Refinements in exception handling. * Improved garbage collector, which now does selective sweeping. On UltraSPARC, LaTTe 0.9.1 is better than the latest Sun JVMs by as much as a geometric mean of 25% on SPECjvm98, and of 30% on Java Grande, in elapsed time measurements. LaTTe was initially based on Kaffe 0.9.0, although much code has now been rewritten in a clean room environment. LaTTe runs on top of Solaris 2.5 or higher on UltraSPARCs. LaTTe was developed by the MASS Laboratory at Seoul National University, with sponsorship from IBM T.J. Watson Research Center. It is free software, being licensed under BSD-like terms. To obtain source code, documentation, and support, please visit http://latte.snu.ac.kr/. This site also contains many publications describing the algorithms used in the LaTTe JVM. We invite volunteers worldwide to join our LaTTe open-source development team and help us implement the exciting, leading edge JIT compiler, VM and instruction level parallelism optimizations to come. One on-going project where we would like help now is to integrate LaTTe back into the current version of Kaffe. === Thank you for your time in reading this announcement. If you have any questions about LaTTe, or would like to join our team, please contact us at [EMAIL PROTECTED], and we will be happy to help to the extent we can. Please feel free to pass this announcement on to other colleagues who might be interested. We hope you will enjoy the LaTTe web site.

"osize" is the correct thing to copy there, because the original memory region presumably was only "osize" bytes long. Pardon me if I am being dumb. Trying to debug the assertion failure was my first brush with Kaffe sources. Could you take a minute to straighten out the following understanding of mine of the gcRealloc() function? The purpose of the function is to reallocate memory, 'mem', to size 'size'. It checks if the current size of 'mem', 'osize', is = 'size' + some additional chunk. If it is, it means that 'mem' can hold chunk of size 'size' and hence it need not reallocate. If 'osize' is 'size' + sizeof (gc_unit), it has to reallocate memory to the requested size, 'size' and not 'osize'. From your message it seems like I am horribly mistaken in my understanding of the function. No, that is exactly correct. But in addition realloc is supposed to not alter the original memory contents, of which there are "osize" bytes. That is why only "osize" bytes need to be copied. The size - osize additional new bytes are just left uninitialized (actually they'll be zeroed I think). -Archie _______ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com
Re: Kaffe/Alpha - bug fix ? finally?
[EMAIL PROTECTED] writes: Finally it seems like I might have fixed the assertion failure that has been bothering me on my Linux/Alpha box. In gcRealloc():kaffe/kaffevm/mem/gc-incremental.c line 1026 it looks like the size of memcpy should be size instead of osize. If the osize (original/old size ?) is less than size+sizeof(gc_unit) isn't it logical to copy size number of bytes instead of osize? Anyways I made the fix in my local sources and ran 'make check'. 25 tests failed but atleast I seem to have gotten past the assertion failure. If this is indeed the fix, change line 1026 in the above said file to memcpy(newmem,mem,size); in the CVS tree. It's good to hear that your assertion failure was fixed, but your fix sortof doesn't make sense. "osize" is the correct thing to copy there, because the original memory region presumably was only "osize" bytes long. However, there may be some other code that calls gcRealloc() with the wrong (i.e., too small) value for the "osize" parameter, causing some data to not get copied. -Archie _______ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com

One might think a quick fix would be to test for NIL and not set the parent, but this causes more grief because the other functions reference parent without checking if its non-nil. Probably not a big problem, just thought i'd let you know. I think this is OK because NIL.parent is never actually used. I haven't verified this rigourously but it makes sense if you think about it, because NIL is the child of all leaf nodes, so NIL has many actual parents. -Archie ___ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com

Re: Nested stack problem
James writes: Ok, I got around the longjmp/setjmp problem w/ Mozilla by building Kaffe w/ --with-threads=unix-pthreads. Things were moving along well when my OJI plugin was a huge monolithic function. Now I am breaking it down so that it intiailizes in the correct order (ie., a single JavaVM instance, multiple plugin instances). The problem is that if I initialize the JVM within a nested function call, and then attempt to use the JVM environment from a function that is nested less than the call which initialized the JVM, the app segfaults. This sounds vaguely familiar.. If I understand correctly, the problem is that kaffe uses the thread inherited from initialization as the first Java thread. Instead, it should really create a new system thread for the first Java thread, and then return within the initialization thread. It might not be too hard to modify kaffe's initialization to do this, if that in fact would solve your problem. -Archie ___ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com

Libtool could not satisfy all declared inter-library dependencies of modules libnative, libzip, libmath, libsecurity. Therefore a static module would be created.

So, IMO all you can do is to code around this problem.
I perhaps misunderstood what you were saying first, and you are of
course
right in that given that current implementations (I haven't tested IBM's
jdk to see if it also has the problem, though) have problems, it is
best to code around the problem (that's what I did once I found the
problem). What I tried to say was simply that it would be nice to
fix (or at least alleviate) the potential problem in Kaffe, as it
seems relatively easy to do (and as the problem has been fixed in
JDK it seems like it was considered a real implementation deficiency).
Then again as there already is a patch that should save space (even if
StringBuffer is used just once), I'm a happy camper. :-)
Tatu-
Aside from the theoretical debate, I'd be interested to hear if
the recent checkin's alleviate the problem you're seeing. Patches

Re: Problem with StringBuffer
Wolfgang Muees writes: I finally found out the reason for 'memory leak' on my Java program, and the culprit in this case was StringBuffer - implementation. I have a lexer (made with JFLex), that uses StringBuffer for constructing the strings for certain tokens. The StringBuffer is reused so that each time a new such token is getting creted, StringBuffer.setLength(0) is called. However, in Kaffe's implementation at least, the actual length of the buffer is not changed. This wouldn't be a big problem in itself, as there's just one StringBuffer instance... But, alas, as Strings StringBuffers are optimized so that when new String(StringBuffer) is called, the character array is actually shared between the string and string buffer, until the StringBuffer needs to change the data (or length of the buffer via setLength()). The problem here is that as soon as I encounter a long token (~4000 chars in this case), _all_ tokens after that will use up the same 4k memory The right solution for this problem is IMO: don't reuse StringBuffer. It is designed primary as an input buffer for a single string.

In any case it's probably not a problem either way you do it. are we supposed to do?

I've applied the following patches -- which are a modification of yours,
and now four tests are failing:
FAIL: Bean.java
FAIL: BeanBug.java
FAIL: Reflect.java
FAIL: ReflectInvoke.java
Could be my changes but they should be equivalent to yours..
I think the problem may be that kaffe calls classFromSig()
on types that are part of a larger string (and not necessarily
at the end of the string) such as function types.. eg:
"(Ljava/lang/String;II)V"

Ok, if you have a class named "int" then the JVM should load

would do in this case because it already uses the name "int"

the regression test check for this is to ensure that
a loaded class (like "int") is not a primitive type.
So we should fix kaffe internally. It shouldn't use "int" as
an internal name for the integer primitive class, because that
clashes with int.class; instead, let's use "I" like we're supposed
to, and maybe define a macro:
#define INTEGER_PRIMITIVE_CLASS "I"

Re: Need GetEnv Java 2 invokation function for JVMDI
Derek L Davies writes: I'd like to get some input on the following problem. To obtain a JVMDI interface pointer the JVMDI spec says a JVMDI client should invoke the Java 2 invokation interface function named "GetEnv". I've only now realized that Kaffe doesn't do Java 2. The JVMDI spec gives this example: JVMDI_Interface_1* jvmdi; (*jvm)-GetEnv(jvm, jvmdi, JVMDI_VERSION_1); So, by the letter of the spec, I'm out of luck trying to implement JVMDI until we have (at least some of) Java 2. Or I could call back directly into the VM as a crude, ugly AND disfunctional stopgap measure. So, is anyone working on Java 2? If so, I'd like to work with them. Otherwise, I'm thinking it seems not too bad to add GetEnv to the invokation interface inside an "#ifdef JNI_VERSION_1_2" block. From a quick glance at the JNI spec it looks like the only new function in the Java 2 version of the table is GetEnv and it's been appended to the table. There is also the matter of changing JNI_CreateJavaVM to recognize "vm_args.version = 0x00010002;" and how ugly that may or may not end up being. How bad would it be to just return the extra table entry regardless of vm_args.version (as long as JNI_VERSION_1_2 is defined) until we get full Java 2? When you say "Java 2" what exactly do you mean? Kaffe has much of the Java2 platform already implemented, though much is also missing. In general though, it attempts to be Java2 compatible. If 'GetEnv' is missing, then we should just add it. There's no need for #ifdef JNI_VERSION_1_2 or anything (we've never used it up to now). -Archie _______ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com

Removing the BufferedInputStream and using only the ByteArrayInputStream that is underneath works. The funny thing is that sun/blackdown: $ java -version java version "1.2" Classic VM (build Linux_JDK_1.2_pre-release-v2, native threads, sunwjit) has _exactly_ the same problem, where _exactly_ the same solution worked.

Ref: http://java.sun.com/products/jdk/1.2/docs/api/java/io/BufferedInputStream.html#skip(long) No code was stolen :-) Kaffe tries to behave like JDK whenever possible and in this case is just using the same default buffer size (eg., 2048).

Re: install errors

If the tree is 'clean', then I get an install command line that contains: ... -export-symbols-regex ^\([Jj]ava\|kaffe\)_ ... if its dirty then I get a command without the '\' in it: ... -export-symbols-regex ^([Jj]ava|kaffe)_ ... That's really bizarre. I build into a separate tree from the source. I can't think of anything else that might be relevant about my setup. Let me know if you want more info from my setup... What do you mean when the tree is clean? You can't install from a clean tree because there's nothing to install... ? I build in a separate tree as well by the way... generally by doing configure, then saying "gmake" then "gmake install". -Archie _______ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com
