#98 NullPointerException in Eclipse causes InitializeWorkspace to fail
DO NOT EDIT OR ANSWER THIS ISSUE. SEE THE ORIGINAL ISSUE INSTEAD:
https://www.jfire.org/modules/bugs/view.php?id=1017
ORIGINAL REPORTER: marco
I just had these exceptions and was unfortunately not able to reproduce them with a fresh workspace. The workspace was compiling fine, after I manually closed the projects, re-opened them and then used the NightLabs SDK's Refresh/Clean/Close/Open feature.

ORIGINAL COMMENT BY marco, VIEW IT HERE:
https://www.jfire.org/modules/bugs/view.php?id=1017
I recommend to simply use a try/catch block with WARN logging and ignore this problem (because it worked fine after close/reopen - the problem was obviously only that it didn't get to close, because the exception happened before).

I added some try/catch blocks, but since I can't reproduce this problem, I don't know if it really helps (or just shifts the problem somewhere else). If anyone ever gets such an NPE again, please either reopen this issue or report a new one.
