Description

CheckingObjectOutputStream seems to be broken in Wicket 7: child components of pages no longer seem to be checked.
The issue can be reproduced by slightly changing org.apache.wicket.core.util.objects.checker:SessionCheckerTest:

line 55 should read

byte[] serialized = serializer.serialize(new InternalErrorPage().add(component));

(i.e. the serialized component is added to an InternalErrorPage first)

The test fails and the serialized session is no longer detected.

The same code on Wicket 6 works just fine.
