IV74405: CRASH IN JIT COMPILED CODE OR GC, OR MEMORY CORRUPTION

APAR status

• Closed as program error.

Error description

• Error Message: Unhandled exception
  Type=Segmentation error vmState=0x00000000
  J9Generic_Signal_Number=00000004 Signal_Number=0000000b
  Error_Value=00000000 Signal_Code=00000001

  Compiled_method=com/google/inject/internal/InjectorImpl.callInCo
  ntext(Lcom/google/inject/internal/ContextualCallable;)Ljava/lang
  /Object;
  .
  Stack Trace: N/A
  .
  This problem has only been seen with the Google Guice framework
  for Java, where the problem usually manifested as a crash in the
  following method:
  com/google/inject/internal/InjectorImpl.callInContext(Contextual
  Callable<T>).
  

Local fix

• The -Xjit:disableLocalCSE option will prevent this problem from
  occuring. Note that that this option will likely lead to reduced
  performance (up to 16% for cpu intensive applications).
  
  An alternative work around that will avoid the problem in the
  cases seen so far is
  
  -Xjit:disableInternalPointers
  
  This typically incurs less than a 2% performance penalty, but
  may not work in all theoretically possible cases of the problem.
  The best advice is to try disableInternalPointers first, and if
  that
  doesn't work then use the more conservative disableLocalCSE.
  

Problem summary

• The JIT compiler performs an incorrect optimization that can
  lead to a stray pointer, which typically results in crashes but
  may also lead to memory corruption. This problem affects Java 6
  and later.
  

Problem conclusion

• The JIT compiler has been fixed to perform the optimization
  correctly.
