TROUBLESHOOTING: JDeveloper will not start

Problem/Symptoms
JDeveloper refused to start. It loaded up to ~600MB of memory and then it freezed. See image below:



Also IE was refusing to load the Home page.

Investigation
Checking the files accessed by JDeveloper, indicated the probable cause:


Resolution
So after removing the files below
  • C:\Documents and Settings\spiros\Local Settings\History\History.IE5\index.dat
  • C:\Documents and Settings\spiros\Local Settings\Temp\hsperfdata_spiros\3736
  • C:\Documents and Settings\spiros\Local Settings\Temporary Internet Files\Content.IE5\index.dat
and Restarting Windows, JDeveloper managed to start.
 
Tip:
Moreover, one of the most useful tips when you have problem with JDeveloper (not starting or performance degradation, crashes etc) is to remove JDeveloper's system directory
The default location is
C:\Documents and Settings\username\Application Data\JDeveloper\
under that directory is a directory named
system11.1.1.4.37.59.23
(for JDeveloper 11.1.1.4.0)
Close JDeveloper and remove it. Upon starting again, JDeveloper will recreate a new fresh one.
WARNING: All your JDeveloper settings (SVN settings, Preferences etc) will be lost!!!!
