Can't open Flash Builder - "See the log file" error.

Question

I have been using Flash Builder 4.5 and for some reason it has stopped opening correctly - I get the following error then it just shuts down.... :
"An error has occured. See the log file."
and if i check the log file it refers to then i see the following text:

This is incredably frustrating as you can imagine as it effectively means i cant work anymore, it is clearly some kind of problem with eclipse but i have no idea what.
I have tried re-installing Flash Builder twice and no luck.
Can anyone help with this???
Thanks !!!!
Elliot.

There is a similar thread with exact same stackstrace and problmes reported with earlier verison of FB. You can check it here http://forums.adobe.com/thread/832073. Thre is also representation of Adobe engineers on this thread. Aprarenlty there are certain updates(Eclipse / java) that FB doen't encourage, post FB is installed in stanadlone mode and workarounds are suggested on this thread to overcome this problem. If you are workign in plugin environment with FB, I guess updates are not affecting FB installtion. Please try out the solutions presented on this thread and let us know.
