Arduino IDE 1.6.5 Fails to start

hi Guys,

Everything was working 100% for ages, but then i decided to add “Processing” to my system as I needed to do some bitmap conversions.

I now have an issue when the Arduino IDE starts it gets to loading boards and then just vanishes…

I ran it with Debug and am getting the following error:

C:\Users\Administrator>"c:\Arduino\arduino_debug.exe"
Loading configuration...
Initializing packages...
Preparing boards...
Starting...

Is there anyone else that has had the same and could advise how i can get rid of it? I tried reinstalling the IDE but it appears java does not forget.
