I have fixed this problem by making DiagnosticContext (inner class in NDC)
serializable. Just added implements serializable to the class definition.
No other code changes. With this change Stack returned from
NDC.cloneStack() is serializable. So we can use it restore NDC later.
Looks like this change does not have any other side effects. Is it possible
to include this in next release of Log4J? Please let me know if some one
feels other wise.
Please reply with your comments.

Subject: Trying to serialize NDC Stack
I trying to put NDC stack in a JMS ObjectMessage and restore NDC when the
message is popped from Queue. I am getting following Exception. I am using
weblogic 5.1 with jdk1.3.
My guess is this problem is due to the fact that DiagnosticContext (inner
class in NDC) that is pushed on to NDC stack is not serializable. Is there
any reason NDC and DiagnosticContext can not be serializable??
Please let me know if I am missing some thing here.
