APAR status
Closed as program error.
Error description
Error Message: The JVM stops unexpectedly and, depending on configuration, will likely create crash diagnostic files including javacore and system core. . Stack Trace: The javacore will indicate that a GPF occurred in libj9jit29.so with InaccessibleAddress: 0000000000000000 Analysis of the system corefile will show that the crash happened in TR_ProfileableCallSite::findSingleProfiledReceiver . This problem only occurs in Java 8 SR5 starting with FP26 when running with AOT enabled.
Local fix
The problem can be avoided with the following JVM command line option: -Xaot:disableSymbolValidationManager This may cause a small performance reduction as the AOT generated code will not be optimised to quite the same extent as when the feature is enabled.
Problem summary
The code assumed that the return value of a function could not be null when, in rare cases, it could in fact return null.
Problem conclusion
An additional null check was added to ensure correctness in all cases. See https://github.com/eclipse/openj9/pull/5617 for more detail. . This APAR will be fixed in the following Java Releases: 8 SR5 FP36 (8.0.5.36) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
