There are many exceptions in the attached log file so the latest one reported here is probably just a side-effect of some earlier exception.
Please provide some steps to reproduce (with a clean user dir) and reopen, thanks.

Yeah, IIRC there was an OOME as well. Hasn't happened again. Can you verify an incomplete bug?

You can reopen and then close/verify. Or just leave it as incomplete.

I have the same problem, it happens randomly and I find that the problem is here:

From change event of Windows2Local/Components/AlarmEditorTopComponent.settings is called PersistenceManager.removeTopComponentForDataObject(DataObject dob) 
and  dob.getCookie(InstanceCookie.class) returns null  it deletes the topcomponent from the registry. 
Subsequently PersistenceManager.getTopComponentPersistentForID creates a new instance. AbstractTabbedImpl.setTopComponents then compares  different instances of same topcomponent and run into AssertionError

I added to PersistenceManager.removeTopComponentForDataObject(DataObject dob) 

InstanceCookie ic = dob.getCookie(InstanceCookie.class);
InstanceCookie ic2 = dob.getLookup().lookup(InstanceCookie.class);
 and the result is an interesting..

ic = null
ic2=InstanceDataObject@342c4b0e[MultiFileObject@73b8337e[Windows2Local/Components/AlarmEditorTopComponent.settings
