Review Comment:
@mbien from the docs, the property name should be passed to both
`WeakListeners::propertyChange` and `addPropertyChangeListener`. As not used
for the latter, I assume this might have been firing for all properties but
only trying to remove a listener on `ClassPath.PROP_ROOTS`?!
@sdedic is right, that second weak listener should be passed
`proj::getProjectWatcher`, or `null`. I think the underlying code can handle
events from alternative sources though, so shouldn't cause a problem?
I (or one of you) can add a second commit here to tidy this up, but need a
call ASAP if we're going to get in rc3.
