  Interesting idea...  Actually, that's just to keep track of the
buffers opened by the plugin.  So probably the best is to use a set
based on object identities, with the WSEditor objects.  Do we have the
guarantee that the WSEditor object does not change between the moment
a file is open and when it is closed?  Object identity looks like more
robust to me than URI comparison, isn't it?
 
  BTW, shouldn't a WSEditor object be returned by Workspace.open()?

  No, but that's also a requirement ;-)  Is there any way to open a
file in read-only using the API?  Other than creating a dedicated
WSEditorChangeListener of course.

  Precisely.

  Perfect!
 
  Thank you, regards,
