Dave Marion commented on VFS-442:
---------------------------------

Started working on #1. I am running into a couple of issues. One seems to be with the the
doAttach method. The javadoc and code seem to indicate that it should thrown an error, but
the test checks to see if the file type is IMAGINARY.
