• Create a JBoss Server in JBDS from a configuration such as all.
• Do a build.sh clean of the AS source code and then call build.sh so that all is rebuilt.
• If I know double click on the on the server from the "JBoss Server View", try changing
  something and save it, I can't because it says something like:

..."server/all/tmp/jbosstoolsTemp" does not exist.

JBDS should be able to rebuild the information for that server without
me having to recreate the server.

See attached screenshot for more info.
