APAR status
Closed as program error.
Error description
Error Message: Unhandled exception Type=Illegal instruction vmState=0x00000000 . The error occurs while running a Java application on a POWER system. . Stack Trace: N/A .
Local fix
No known workaround.
Problem summary
The problem is caused by the JIT compiler omitting a memory barrier instruction during the escape analysis optimization; the instruction is required as the POWER architecture has weakly-ordered memory consistency.
Problem conclusion
The escape analysis is updated to correctly insert the memory barrier instruction. . This APAR will be fixed in the following Java Releases: 7 R1 SR2 FP10 (7.1.2.10) 6 R1 SR8 FP3 (6.1.8.3) 6 SR16 FP3 (6.0.16.3) 7 SR8 FP10 (7.0.8.10) .
