Sven Meier commented on WICKET-6704:
------------------------------------

You've written it in your code comments already: This is weird!

I don't have a clue why this special combination of fields (Future, 
PropertyChangeSupport subclass in superclass) fails this way, let alone why 
this should result in a JVM crash.

If this is critical for you, I suggest you skip the magic and do with a 
standard ObjectOutputStream instead:
{code:java}
frameworkSettings.setSerializer(new 
JavaSerializer(application.getApplicationKey()) {
  @Override
  protected ObjectOutputStream newObjectOutputStream(OutputStream out) throws 
IOException
  {
     return new ObjectOutputStream(out);
  }
});

{code}

> JavaSerializer.serialize causes the JVM crash !

>                 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
>            Priority: Critical
>         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)
