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(
at Source)
at weblogic.rmi.internal.BasicServerRef.invoke(
at weblogic.rmi.internal.BasicServerRef$
at weblogic.rmi.internal.BasicServerRef.handleRequest(
at weblogic.rmi.internal.BasicServerRef.access$300(
at weblogic.rmi.internal.BasicServerRef$

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
