Hi,
Assuming you use CGLib:
CGLib classes could cause this problem, it makes sense since:
- It does not occur in a single jvm, the enhanced classes are available
there.
- It does occur when read from a different jvm *or* restarted jvm: The
enhanced classes are no longer available there.
Hi,
I did some more research (since I am intrigued by the subject) with the
following results:
- If you have enhanced cglib classes in your session and they are serialized
and later deserialized by a different jvm (for instance after restart)
you'll get a ClassNotFoundException. Since it can't
Thank you Lars, unfortunately we still haven't found any actual cglib
proxies in our session. So it goes.

We just discovered that if we use SecondLevelCacheSessionStore the
problem goes away. From there we determined that the setting
Application.get().getPageSettings().setAutomaticMultiWindowSupport(false);
is the lynch pin. We still don't know why this resolves the problem.

On Tue, Mar
what else did you use if you didnt use SLCS?
Because if you use the HttpSessionStore then we dont do anything with
serialization..
Thats all tomcat or app container itself

So that at least eliminates the possibility that cglib is somehow involved.

That did not take care of our problem. We are examining our session
to see whether it mistakenly contains some sort of cglib proxy -- our
typesafe model, or maybe something from Hibernate.
Thank you again for the help.

It seems that the byte array on that side isnt correct. Do you have a
setup/testcase for this? Do you get it on other app servers?

We run JBoss and haven't tried this on other app servers. Could the
fact that we're running Java 6 be relevant? The specific type code in
the exception varies each time, and this occurs every time we fail

We don't a test case, but if you have a JBoss cluster we
Using the HttpSessionStore pushes this exception to JBoss. It seems
that something in the session just can't be deserialized by a separate
jvm.

Seemingly yes. If we write the session to disk, stop the jvm, restart
the jvm, and then read the session from disk on the same server we
get this exception.

Couldn't missing SerialVersionUUID cause this? Doesn't seem likely
though, I'd expect much saner exception in that case.

Are these nodes on the same machine or are you running different machines?
