...The crash happens when the JIT triggers J9HOOK_VM_METHOD_RETURN for the JVMTI MethodExit event. JVMTI MethodExit doc: https://download.java.net/java/early_access/jdk21/docs/specs/jvmti.html#MethodExit.
A NULL (valueAddress / returnValuePtr) is passed by the JIT. The segfault occurs when the NULL returnValuePtr is dereferenced in jvmtiHookMethodExit.
Requesting the JIT team to look at this failure since the NULL returnValuePtr is passed from the JIT. fyi @0xdaryl.

0x7fff2248b6e4 b 0x7fff2248b52c <--- return addressFrom the inlining table of this body, inlined site 2 is String.checkBoundsBeginEnd(III)V (J9Method 0x7fffb416ad38), which agrees with the stacks shown in Babneet's comment above. At offset +62 its bytecode has a (void) return0 instruction
The JIT generates exit hooks here: https://github.com/eclipse-openj9/openj9/blob/b47a6d454b305feeb6c45b173715e5a9471aa254/runtime/compiler/ilgen/Walker.cpp#L6825-L6837 It looks like it's expected that we would pass null when exiting a method with void return type
So I think that the null is correct, and that the bug is instead that we passed the J9Method of substring when we should have passed checkBoundsBeginEnd (at ** above). I'm guessing that from the point of view of the hook, the null is unexpected because substring returns a value
I'm trying to figure out why we passed the wrong J9Method. Since this is an AOT body, it might be a relocation problem

>> Success condition was not found: [Return code: 0]
cmdLineTester_jvmtitests_8_FAILED@dsouzai found that TR_RamMethodSequence always patches in a pointer to the J9Method of the outermost method:
I'm attaching a repro that (at least on PPC64LE Linux) reliably passes the wrong J9Method to jitReportMethodExit, which then crashes. Backtrace:
fillInJValue+0x100 (0x00007FFFB254ED60 [libj9jvmti29.so+0x1ed60])
J9HookDispatch+0x1e0 (0x00007FFFB8181960 [libj9hookable29.so+0x1960])
old_slow_jitReportMethodExit+0x18c (0x00007FFFB37837CC [libj9jit29.so+0xc437cc]) It just inlines a void method into a non-void method in an AOT compilation with JVMTI method exit tracing enabled
Repro.java, testagent.c. To run (with a given $jdk):
$ gcc -fPIC -shared -I"$jdk/include" -I"$jdk/include/linux" -o libtestagent.so testagent.c
$ export LD_LIBRARY_PATH="$PWD${LD_LIBRARY_PATH+:}${LD_LIBRARY_PATH:-}"
$ "$jdk/bin/javac" -g Repro.java
$ "$jdk/bin/java" -Xshareclasses:destroyAll
$ "$jdk/bin/java" -Xshareclasses -agentlib:testagent -X{jit,aot}:'forceAOT,limit=go,count=1,disableAsyncCompilation,disableGuardedCountingRecompilation,disableDelayRelocationForAOTCompilations,tryToInline={*.inline*}' ReproI can see from the core that the incorrect (non-void) J9Method is passed alongside null in the same way as I described in my previous comment. Additionally, logging shows that the trees specified the correct J9Method, and that the constant materialization sequence is indeed relocated using TR_RamMethodSequence, confirming that the bug is due to the problem that Irwin identified
To fix this, I'll generalize TR_RamMethodSequence relocations so that they can also deal with the J9Method of any method that has been inlined in the compilation

1 year ago I've opened a fix for this. Rather than generalize TR_RamMethodSequence to support inlined methods, I've removed the paths that would require such support
