Error description
Error Message: A GPF/ABEND occurs during JVM start-up. This only occurs for Java 6 and later releases. .

Local fix
This problem can be avoided by deleting the shared class cache semaphore and shared memory before starting the JVM, or by disabling ahead-of-time compilation with the -Xnoaot option, or by disabling the shared class cache completely. Note that these workarounds may cause start-up performance impact or memory footprint growth, or both.
Problem summary
The issue is that the cache was populated with AOT code from both non-compressed and compressed JVMs, which are incompatible.
Problem conclusion
This defect will be fixed in: 6.0.0 SR10 . The JVM AOT compatibility code has been updated to catch this small window of time in which an incompatible JVM will populate AOT code into the cache. . To obtain the fix: Install build 20110612 or later
Temporary fix
