APAR status
Closed as program error.
Error description
Error Message: N/A . Stack Trace: N/A . A Java exception handler receives either a null reference, or a reference to an exception object other than the one just caught.
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: 6 SR16 FP40 (6.0.16.40) 6 R1 SR8 FP40 (6.1.8.40) 7 SR10 (7.0.10.0) 7 R1 SR4 (7.1.4.0) .
