Note that the original description is _slightly_ wrong: the target class itself
or its ctor has to be package private for this to happen.

> Key: WICKET-4324
> URL: https://issues.apache.org/jira/browse/WICKET-4324
> Project: Wicket
> Issue Type: Bug
> Components: wicket-spring
> Reporter: S Mathez
> Labels: proxy
>
> A CGLib proxy created by LazyInitProxyFactory may cause
> java.lang.IllegalAccessError when the target class has "package-private"
> method.
> I think the root cause of this problem is the choosen strategy for naming
> proxies (see WICKET-1162) : after adding "WICKET_" before the package name of
> the target class, the proxy becomes a member of a new package. (This
> behaviour is different as which is used by CGLib DefaultNamingPolicy).
> Why not adding "_WICKET" *after* the name of the target class ?
