Problem with two files in same dir, names differ only by case

When two .jsp or .xhtml files are in the same directory, and their names differ only by case then opening with the "JBoss Tools JSP Editor" or "JBoss Tools HTML Editor" always opens the "first" one of them regardless of which is actually selected.

It is not possible to open the other file with the jboss editors. However selecting "open with" and choosing a non-jboss editor works fine.
