IV03364: JAVA.LANG.STACKOVERFLOWERROR WHILE RUNNING JVM IN DEBUG MODE.

APAR status

• Closed as program error.

Error description

• Error Message: java.lang.StackOverflowError
  .
  Stack Trace: N/A
  .
  

Local fix

• Exclude from compilaiton the two methods at the top of the Java
  stack prior to the recursive call that lead to the stack
  overflow exception.
  -Xjit:exclude={*<method signature>*},exclude={*<method
  signature>*}
  

Problem summary

• A JIT optimization present only in debug mode passed the
  incorrect parameter to a method X. (The first parameter was
  replaced with the receiver object). In method X, a call was made
  to the first parameter's implementation of X, thus resulting in
  an infinite recursive call.
  

Problem conclusion

• This defect will be fixed in:
  6.0.1 SR1
  6.0.0 SR10
  5.0.0 SR13
  .
  The JIT optimization was fixed to avoid incorrectly altering the
  parameter to a method.
  .
  To obtain the fix:
  Install build 20110731 or later
  

Temporary fix
