Hello.
I'm not sure if there's a minor typo but I cannot find the error in it. Can
you guys look? In System.c we have:
JNIEXPORT void JNICALL
Java_java_lang_System_setMemoryAllocationListener0(JNIEnv *env, jclass cla,
jobject listener)
{
jfieldID fid =
(*env)->GetStaticFieldID(env,cla,
This is an OpenJDK 9 build. Can you explain? I'm very interested in getting
all the details understood. Hey thanks!

Hello.
Thanks for taking time. We had a quick question about the Java to C mappings
in the JDK. For instance the System.java has a corresponding System.c and even
a System.o.
We find these without too much problem. However many of the "core" packages

Where in the Makefile would we add this to silence to deprecated warnings from
GCC compiler?
-Wno-deprecated
Who thought this would be fine? To run this seem falty. ok
Where in Makefile do we add this - to suppress deprecation warnings - to our
personal builds.
Thanks.

Can you explain how to remove the requirement for comments in the OpenJDK build
in the Java source files? It's really killing my schedule to have to reinsert
comments by hand.
Thanks.

Inside java.c there is a JLI_Launch which purports to be the launching or entry
point for the JVM. The last line shows:
return JVMInit(&ifn, threadStackSize, argc, argv, mode, what, ret);
This is given apparently as a function call that will return an int. However

Quickly, where do we look? I can't seem to find where the "javac" command is
called in the C interface.
Where is the java code that runs the parser/compiler? Ok, thanks gotta run
ably.

Where does Java handle pass by value? Where can I see that implementation?
Great. Thank you.
I am presuming the JVM interpreter is defined/implemented in the the hotspot

I cannot seem to find *any* instruction in it that gets called by a simple

Can I ask you guys a quick question. Does the VM development team plan on
implementing any pure pass by reference. Also I think we would like security
and RMI integration going forward with the VM directly. No way to hook memory
allocation seems like a miss.
Let me know with some feedback.
