One of the things that isn't on the list is how the Workspace
currently copes with multiple IResources which map to the same
filesystem Location.  These occur when you're building projects using
linked resources, or have created multiple projects with overlapping
locations.

Currently Eclipse treats multiple workspace resources (with same
location) separately.  They open to separate editors, have separate
local histories, have separate markers, etc.  See:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=247647 for the sorts of
things that go wrong.

It seems very difficult if not impossible for ISVs to integrate
properly if the platform really gives you multiple IResources for a
given location (with findFilesForLocation()).  It certainly seems
non-trivial to decide on which File a marker should be created, or
which IFile should be opened when all you've got is the path provided
by an external tool.

Am I naive in believing that if they really are the same file on disk,
they really should map to a single IResource (or multiple IResources
with the same set of attributes)?

Cheers,
