      Trying to migrate from 4.2.1GA to jboss-5.0.0.GA (jdk6 download) my app finally seems to deploy fine but I get the following exception on the client side (swing client):

      The method to be invoked is from the ClientSessionBean/remote interface.
      Any ideas?

      Env:
      # java -version
      java version "1.6.0_10"
      Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
      Java HotSpot(TM) Client VM (build 11.0-b15, mixed mode, sharing)
      # uname -r
      2.6.26-1-686

      Thx in advance.

          Thanks for reporting this.

          Running the Unit Tests under JDK6 for the ejb3-common project show this failure as well.

          https://jira.jboss.org/jira/browse/EJBTHREE-1622

          You can put a watch on the issue for updates. ;)

          In the meantime, you can workaround by:

          * Running in JDK5
          * Moving your primitives to wrappers (ie. char[] > java.lang.Character[])

            Ah, the ClassLoader Array Syntax thing.

            http://bugs.sun.com/view_bug.do?bug_id=6434149

            You can also do:

            -Dsun.lang.ClassLoader.allowArraySyntax=true


            ...in System properties to workaround.

            That's untrue. I misread the problem as dealing w/ primitives, but it's arrays.

            I've committed the fix to ejb3-common and this will be available in the next release.
