[news.eclipse.newcomer] java.lang.IllegalStateException: Workspace is cl

[kja.eswar@xxxxxxxxx (Eswar)]

Hi all,

I'm writing a plugin, and I'm blocked on a strange behavior. My plugin 
contains a wizard, and as soon as I start a debug session for it and try 
to open the wizard I get the following message on the console:

Unhandled event loop exception
Reason:
Workspace is closed.

In the .log file, I find the exception shown at the end of this messasge. 
I'm running Eclipse 3.1 . 

Can someone give me a hint? I'm totally lost!
Thanks in advance,
Eswar
