you are doing something you're not supposed to ... from the javadoc:
	 * Returns the active nested editor if there is one.
	 * <p>
	 * Subclasses should not override this method
	 * </p>

That's not to say you can't create public IEditorPart getCurrentEditor() 
and return getActiveEditor().

As to why ... that's partly lost in the mists of time, but basically as 
public API it states you can't override or extend (the framework expects 
certain return values and a certain behaviour).


One plugin ignored the warning, overrode the method, and changed the 
behaviour that if there was no active editor (just a Composite page) it 
return the MPEP ... then suddenly they got an infinite loop.

It's not that you can't ignore those kinds of warnings ... but perhaps 
you shouldn't.
