Emond Papegaaij commented on WICKET-6353:
-----------------------------------------
I've added some docs. I can understand that the code seems strange, but it's
simply copy-pasted from the superclass. Unfortunately, ObjectInputStream is not
designed very well, so copy-pasting and reflection are the only way to get this
working.
> Proxy deserialization fails due to classloading issues

> Key: WICKET-6353
> URL: https://issues.apache.org/jira/browse/WICKET-6353
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 7.6.0
> Reporter: Emond Papegaaij
>
> JavaSerializer.ClassResolverObjectInputStream overrides resolveClass to
> resolve classes via the Wicket ClassResolvers. This does however not happen
> for resolveProxyClass.
> An example of how this can go wrong:
> * A page with a large component tree is deserialized (war).
> * LinkedMap (used in MarkupContainer) is loaded in a parent ClassLoader (ear).
> * Via this stack, a proxy is hit implementing Spring classes (from the war)
> * Due to LinkedMap determining the latestUserDefinedLoader, the ear-loader is
> used for the lookup of this interface, which fails
> Unfortunately, writing a testcase for this is not easy, so I only have a
> proposed fix: see the classloadingfix branch
