fixed in scope of #235687 - IllegalArgumentException: Root cannot be null
Sorry to REOPEN, dunno if the comment will be seen if not. I'm having the same error in a mvn project when ctrl+clicking a class name defined in a dependency, for which I've downloaded sources before. The only way to see the src is manually browsing dependencies (after guessing in which one is the class of interest) and clicking on the class.
