This is a JVM crash. Usually I would recommend updating to a more recent JDK (a good idea anyway) and if the problem still occurs sending it to Sun (now Oracle, I guess). But given where it is aborting I suspect that your NIC driver might be bad. Try updating the driver to the latest level. If that does not solve the problem, try to code on another machine. If the problem happens there also, send the issue to Sun/Oracle.
Another possibility: what database are you using and what driver? Be very specific as to which driver. If could be the driver that is crashing.
