APAR status
Closed as program error.
Error description
Error Message: Crash in the GC, JIT compiled method or VM is possible as well as invalid values being passed around a JIT compiled method. . Stack Trace: N/A . This issue only occurs on 64-bit Z series (zOS64 and zLinux64) platforms where the use of high word registers is enabled. All other platforms are unaffected by this issue.
Local fix
This issue can be worked around using the -Xjit:disableHighWordRA option.
Problem summary
The JIT compiler encounters an invalid register state during register allocation when an associated internal data structure becomes fully saturated. This could occur in a block of code where many values are live at the same time.
Problem conclusion
The JIT has been updated to prevent the generation of invalid register state during register allocation in the scenarios where this problem can occur. . This APAR will be fixed in the following Java Releases: 7 SR10 (7.0.10.0) 8 SR3 FP10 (8.0.3.10) 7 R1 SR4 (7.1.4.0) 6 R1 SR10 (6.1.10.0) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs. For those running stand-alone, information about the available Service Refreshes and Fix Packs can be found at: https://www.ibm.com/developerworks/java/jdk/
