I wrote a small example. If I run the following code as a Netbeans Platform Module a new Netbeans instance opens with the standard start TopComponent. When I open the test TopComponent anything works including resizing with two TopComponents open. Then I switch to the start TopComponent tab and resize the Netbeans window. If I switch back to the test TopComponent tab the Java3D part is still in the size before switching to the other TopComponent.
