Description

• 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)
