Anything that results in segmentation fault inside JRE and a core dump is most likely to be a JVM or JIT compile bug. I do not think there is anything I could to help you other than suggesting to upgrade to the latest JRE 1.7 or downgrade to the latest JRE 1.6 and see if that makes any difference or reporting the problem to Oracle.
