IJ15764: CRASH DURING JIT COMPILATION

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)
  .
