Local fix
-Xjit:disableLocalReordering would work around this problem; this turns off a JIT optimization that should not affect performance noticeably
Problem summary
The problem is caused when a pointer into the middle of a Java array (an internal pointer) is not updated by the GC because of a bug in a JIT compiler optimization.
Problem conclusion
This defect will be fixed in: 7.0.0 SR3 6.0.1 SR4 6.0.0 SR12 5.0.0 SR15 . The JIT compiler has been updated to prevent the problem from occurring.
