Re: bad file descriptor with jdk1.2.2
Hallo, d>I have verified the path to the file, the integrity of the file and d>changed permissions using 1.2 as a guide. Nothing sticks out. Perhaps strace helps? MbG, Ekkehard -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
jdk1.2.2-RC1 on Slackware-7.0.0 i386 problem
Hi everybody, Maybe I've missed some some note on hardware dependencies of the upcoming 1.2.2 port for i386, but in my case RC1 crashes during early stages of startup on 486 box, while working smoothly (except well-known bugs :-) on P-IIs running the same system (Slackware distribution vs#7..0.0, 2.2.13 kernel linked with glibc 2.1.2. strace gives not so much consumer info - SIGILL Illegal Instruction happens just before lstat()-ing system information after brk(<0x804c000>) before successive brk(<0x804d000 appearing on P-II>). Should I report a bug? Any help would be highly appreciated. The origin of the problem is incompatibility of RMI protocols for 1.1 against 1.2, which uses reflection based stubs and introduces Activation mechanism, heavily used by the current ref implementation of Jini, otherwise the easiest solution would be to use 1.1 for somewhat out-of-date jinn member carriers.

JDK 1.2.2 RC2 VolanoMark results
The JDK 1.2.2 RC2 release of the Java-Linux port does the best job yet at running VolanoMark. Here's what I get for the loopback performance test in messages per second: Sun JDK 1.2.2 RC2 Linux JITno JIT --- Native931 513 Green 956 478 and here's what I get on the network scalability test in messages per second for 1,000 through 4,000 simultaneous connections (using green threads with the JIT and disabling the use of socket timeouts on the server): Java Platform 1000 2000 3000 4000 == Sun JDK 1.2.2 RC2 Linux 1166 690 463 (*) (*) The 4000-connection test failed with: java.lang.StackOverflowError at java.security.AccessController.doPrivileged(Native Method) at java.net.Socket.getOutputStream(Socket.java, Compiled Code) at COM.volano.mby.(Unknown Source) at COM.volano.Main.run(Unknown Source) at java.lang.Thread.run(Thread.java, Compiled Code) I needed to disable the use of socket timeouts on the server -- something our customers can't do without bad side effects -- in order to work around this problem: Bug Id 1578, "java.net.SocketException: Interrupted system call" http://www.blackdown.org/cgi-bin/jdk/incoming?id=1578 That's a dramatic improvement over the network scalability of JDK 1.1.7 Version 3 on Linux, and far better than the current limit of 500 connections with IBM's JDK 1.1.8. Better yet, I did not need to recompile the Linux kernel nor rebuild the LinuxThreads library in order to run the test, as is required for IBM's Java VM on Linux. I just set the per-process file descriptor limit to 4096 and ran! For comparison scores, see: The Volano Report http://www.volano.com/report.html Looking forward to RC3!

Sun and Inprise?
Anyone from the Blackdown team care to comment on: http://www.computerworld.com/home/news.nsf/all/9912035javalinux wherein a "source close to Inprise" claims that Inprise and Sun are going to announce that they are "porting the Java 2 development kit to the Linux operating system". No mention of the Blackdown team's current porting effort is made in the article. If this is true, I'm going to be seriously PO'd at Sun.

Java 2 Port to Linux doesn't include Blackdown...
http://www.computerworld.com/home/news.nsf/all/9912035javalinux What is this? I thought Sun was going to continue helping Blackdown to get the port done, now it looks like Inprise and Sun are going to do it ( Java - JBuilder 3 love) and there is no sign of Blackdown in here. Did you (Blackdown) just get dumped by Sun? Or did you know about this? -- [ Riyad Kalla ] [ [EMAIL PROTECTED] ] [ CS - Major ] [ University of Arizona ] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Illegal instruction...
Hello, I finally installed jdk-1.2.2-RC2-linux-i386-glibc-2.1.2.sh. There is only a little problem (well, a big one). Every time .java_wrapper (that means for everything, I guess) is called, I get the following message: Illegal instruction The same thing happens when I am root, or a simple user. What could I do about this ??? Papi __ Do You Yahoo!? Thousands of Stores. Millions of Products. All in one place. Yahoo!

I think that announcement has been postponed.
