Local fix
Problem summary
The problem is caused when the application is run in balanced or metronome GC mode, and an array is accessed, at a program point having many other computations nearby causing high "register pressure". An internal counter in the JIT overflows and the JIT crashes as a result.
Problem conclusion
The JIT has been fixed to cope with effectively unlimited register pressure around array accesses. . This APAR will be fixed in the following Java Releases: 6 SR17 (6.0.17.0) 7 R1 SR2 (7.1.2.0) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs. For those running stand-alone, Java maintenance is available from: https://www.ibm.com/developerworks/java/jdk/
