Access violation during compilation

843829 Newbie
Currently Being Moderated
We have a customer that has been experiencing a failure in the HotSpot compiler while running our application. The client has managed to create a scenario where they can fairly consistently reproduce the problem. When the failure occurs they get a hs_err_pid*.log file with a EXCEPTION_ACCESS_VIOLATION (0xc0000005), the compilation task is always within the same method.

They are running the YourKit Profiler and this seems to be a possible contributing factor. Turning this off or turning compilation of the method off does seem to resolve the problem, however as the issue first occurred after the application had been up for a few months they are concerned this has merely put the issue off and it may occur again or in another method compilation.

We’ve also captured the output from –XX:+LogCompilation and this shows a fragment of the compile of the method with the optimizer and idealLoop incomplete.

They are also running java 1.5 build, moving to java 1.6 is not really an option as this would involve an upgrading to a later version of our application.

Is this a know problem with the 1.5 HotSpot compiler? We are being pushed by the client to explain why this has suddenly started happening and confirm that the issue or similar compiler issues will not occur again if they turn off the profiler and/or stop the method from compiling.

Any insight greatly appreciated. I can supply either the complete fragament or the whole compile log but these are large.

    Most common cause of that is JNI or 3rd party libraries that do JNI.
    A bug in those can cause ill effects much later in an application.

    It would be very rare to see that originate solely based on the VM.
    I am not sure that I have seen that exception, as reported on these forums, originate from the VM in years (before 1.5 and perhaps before 1.4).
    They are running the YourKit Profiler
    I believe profiling requires using JNI interface - the debugging API.
    Misusing the API would cause problems.
    64-Bit Server VM (1.5.0_20-b02 mixed mode)
    That said the 64 bit implementation was rather new at the time. So it could be a bug in the VM.
    ...or in another method compilation
    Certainly a valid concern.
