Martin Tzvetanov Grigorov commented on WICKET-6704:
---------------------------------------------------
WicketObjects' methods are static, so it is not possible to override them.
What is the actual stack trace that leads to WicketObjects in your case ?
> JavaSerializer.serialize causes the JVM crash !
> -----------------------------------------------

> Key: WICKET-6704
> URL: https://issues.apache.org/jira/browse/WICKET-6704
> Project: Wicket
> Issue Type: Bug
> Components: wicket-core
> Affects Versions: 8.5.0
> Environment: Windows 7, but probably it's NOT OS dependant
> Reporter: Joe K
> Assignee: Martin Tzvetanov Grigorov
> Priority: Major
> Attachments: jvm-crash_from_wicket.zip
>
>
> * when trying to serialize my custom object with a non-serializable field by
> JavaSerializer.serialize the JVM crashes instead of throwing the regular
> NotSerializableException !
> * when trying to serialize THE SAME object by java ObjectOutputStream then
> it's handled correctly and NotSerializableException is thrown
> * I'm attaching the very simple source code (Maven project), 1st test
> simulates the wicket issue (JVM crash) and 2nd test simulates the correct
> handling by java ObjectOutputStream
> * the attached example is just the simplification of very large project
> which is massively used by the users, so in fact it's critical for us
>
> * java: 1.8 (probably doesn't matter, tested on 1.8.0_162 and 1.8.0_221)
> * wicket: 8.5.0 (probably the problem is also in other versions)
