TROUBLESHOOTING: JDeveloper closes unexpectedly with no error message

Problem
Sometime JDeveloper might start acting funny and in worst case might crashes or closes unexpectedly.

The good thing is that all JDeveloper's setting are stored under its system directory. More regarding this directory in Change JDeveloper's system directory (system11.1.1.x.x.xx.xx).

Solution
Close JDeveloper  (if you are running it)

Go where the system dir is located, typically under
C:\Documents and Settings\username\Application Data\JDeveloper\
and remove it

Start JDeveloper. JDeveloper will recreate a fresh system dir automatically.

Warning! 
All you JDeveloper Preferences, SVN settings, embedded WLS configuration will be lost!!
