    ArraySet error

      Hy every body
      I use weblogic 9.1 in order to obtain metric with JMX and metric. and I 've the following error:

      java.lang.ClassCastException: weblogic.utils.collections.ArraySet
      at weblogic.iiop.IIOPOutputStream.writeObject(IIOPOutputStream.java:2203)
      at javax.management.remote.rmi.RMIConnectionImpl_WLSkel.invoke(Unknown Source)

      at weblogic.work.ExecuteThread.execute(ExecuteThread.java:207)
      at weblogic.work.ExecuteThread.run(ExecuteThread.java:179)

      I think than my code is not the cause of the issue , but:

      ObjectName on = new ObjectName(className);
      set = c.queryMBeans(on, null);

      when they are a lot of mBean, its work ("com.bea:Name=JTARuntime,Type=JTARuntime,*")
      but when I want only one mbean, it doesn't work, I have the error.

      the issue has begin when I have installate an apach plugin in order to cluster weblogic ( It's work, and I need it). The issue is also present on the other domain, who are not use with apach, and when apach is closed.

      I have search but i had'nt found anything
      Please, help me !

      ps : excuse the Syntax, I'm not used to speack English
