IV90106: JAVA CRASHES WHILE DEREFERENCING CURRENT EXCEPTION OBJECT

APAR status

• Closed as program error.

Error description

• Error Message: N/A
  .
  Stack Trace: N/A
  .
  The JVM spuriously crashes or throws NullPointerException while
  attempting to dereference the current exception object from
  JIT-compiled code.
  

Local fix

• The problem can be avoided by passing -Xjit:disableThrowToGoto.
  This option may have a minor impact on performance, but it can
  be restricted to the problematic method.
  

Problem summary

• For an exception throw operation, the JIT compiler attempts to
  statically determine the corresponding exception handler, and
  optimize the throw into a direct jump if possible. If the
  intermediate code contains a certain rare pattern of use of the
  caught exception, this transformation could fail to properly
  pass the exception object to the handler.
  

Problem conclusion

• The compiler has been modified so that the exception object will
  be passed to the handler correctly.
  .
  This APAR will be fixed in the following Java Releases:
   8 SR3 FP20 (8.0.3.20)
  .
