Local fix
N/A
Problem summary
The JVM will convert SIGBUS signals originating from the execution of Java code into a InternalError exception. When an arraycopy is executed against a DirectByteBuffer the JIT uses a native helper to perform the copy, but if this copy results in a SIGBUS the JIT would not convert to an exception because the signal occurred outside JIT compiled code.
Problem conclusion
The JIT was modified so that a SIGBUS signal from a JIT helper routine called from JIT compiled code will be converted into a InternalError exception. . This APAR will be fixed in the following Java Releases: 8 SR5 FP22 (8.0.5.22) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
