Serialization problem for ConcurrentHashMap
Hello! Sry for my English. I've get the next error while wicket page had
serialized a page:
2012-12-12-qtp22803607-17--ERROR-org.apache.wicket.serialize.java.JavaSerializer:Error
serializing object class

org.apache.wicket.core.util.objects.checker.CheckingObjectOutputStream$ObjectCheckException:

A problem occurred while checking object with type: java.lang.Object

java.util.concurrent.locks.ReentrantLock.sync[write:18][write:19]
[class=java.lang.Object] <----- field that is causing the problem
It's very strange in my opinion that ReentrantLock.sync cannot be
serialized. It's bug of the Wicket or my app?
Thanks.

Sry I've tried to reproduce this bug in quickstart project but with no
results. I
can't investigate anymore because right now I am under time pressure...
The bug regular occurs in Apache Caynnen Object Context which I pass from
one
Page to a constructor of a Page will be forwarded. And this each time
throws the
exception.

Re: Serialization problem for ConcurrentHashMap

Hi,
java.util.concurrent.locks.ReentrantLock.Sync is Serializable, so it looks
like a bug in Wicket ..
Please create a simple quickstart that demonstrates the problem and attach
it to Jira.
