APAR status
Closed as program error.
Error description
Error Message: A segmentation error raised by the JIT compiler with vmState=0x00000000 . Stack Trace: N/A . This problem is specific to the zSeries code generator and therefore can only occur when running on the zOS or zLinux IBM JVM.
Local fix
N/A
Problem summary
The problem is caused when, as part of its optimizations, the JIT compiler incorrectly removes a bytecode from the compiler's intermediate language. While this operation was safe in some cases, it was still being performed in cases where it was not safe. This can cause a variety of problems, but the only known symptom is a segmentation error caused by accessing the stale version of an object which has been moved by the Garbage Collector.
Problem conclusion
The JIT compiler has been updated to perform additional checks to make sure that the bytecode is only removed when it is safe to do so. . This APAR will be fixed in the following Java Releases: 8 SR2 FP10 (8.0.2.10) 7 SR9 FP30 (7.0.9.30) 7 R1 SR3 FP30 (7.1.3.30) 6 R1 SR8 FP20 (6.1.8.20 ) .

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/ June 10, 2016: Updated Release information to include 6.1.8.20
