APAR status
Closed as program error.
Error description
Error Message: The JVM exits unexpectedly, with crash data written as per operating system and JVM configuration. . Stack Trace: The javacore will show a crash in module libj9jit, and one or more of the registers will hold the 32 bit value for -1 (00000000FFFFFFFF). Use of a native debugger will show the crashing method is TR_J9VMBase::getResolvedVirtualMethod(TR_OpaqueClassBlock*, int, bool), called during inlining. .
Local fix
The method that was being compiled can be excluded from JIT compilation. e.g. if the method was in package a.b, class C and called 'method': -Xjit:exclude={a/b/C.method(*},dontInline={a/b/C.method(*}
Problem summary
An error in the JIT compiler resulted in an incorrect vtable offset being passed to getResolvedVirtualMethod.
Problem conclusion
The JIT has been modified so that a valid vtable offset is stored in all cases. For more details: https://github.com/eclipse/openj9/pull/6993 . This APAR will be fixed in the following Java Releases: 8 SR6 FP5 (8.0.6.5) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
