    Hotspot Server VM crashes with JBoss 3.2.3

    Rudolf Frank Newbie

      Hi,

      When I start JBoss 3.2.3 with the -server option the JVM crashes at the deployment of a specific MBean. This didn't happen with JBoss 3.2.1. I already sent a bug report to Sun, but they told me to ask JBoss to investigate this further.
      Here follows the Sun Bug Report:

      Hi,

      Thank you for reporting this issue.

      Please ask JBoss to investigate this issue further. Since JBoss appears to trigger this failure, the developers of JBoss will be able to examine their product, isolate the cause of the behavior, and, if necessary, provide us with a detailed report.

      Regards,
      Jonathan

        • 1. Re: Hotspot Server VM crashes with JBoss 3.2.3
          Juha Lindfors Master

          It is clearly a bug in their reflection package. No amount of investigation on our part is going to make that any more clear.

          Tell them to fix their JVM.

          • 2. Re: Hotspot Server VM crashes with JBoss 3.2.3
            Adrian Brock Master

            The stacktrace shows an access to a simple getState() method using
            reflection.

            Your memory dump shows the permenant generation at 97% , so I'd guess
            it is a gc problem. Especially since reflection objects are held in the permenant generation.

            Do Sun want us to debug their reflection implementation or garbage collection? :-)

              2 * WORKAROUNDS

              I had the same problem and I have noticed that the permanent generation size was reaching 99% usage although the MaxPermSize (default=64m) was higher (see below part of the dump) so I have increased the minimum permanent generation allocation and it works!!!!

              Try to add -XX:PermSize=64m to your JVM parameters.

              Anyway this is only a workaround and we still need to wait for sun to fix this.

              Note: this only happen on 'server' mode and not on 'client' jvm mode so this could be another workaround you may want to use (second workaround ;-).
