Description scanti 2017-09-12 09:37:08 UTC 
Inside o.n.core/src/org/netbeans/core/NbURLDisplayer.java at line 213 there is this code: 

((NbURLDisplayer) URLDisplayer.getDefault()).htmlViewer = null;

In our RCP application, we had to implement our own URLDisplayer, then a user of ours reported a ClassCastException because of the aforementioned code. 

I think you should add a method like reset() to URLDisplayer instead of doing the cast.
