Description Vishnu CLA 2005-11-15 20:03:54 EST 
During Eclipse startup, displays the workspace selection window and crashes 
when the mouse is moved over the workspace selection window giving the 
following error.

JVM terminated. Ext code=1.
And the console shows the error - "Eclipse received an X Window system error. 
The error was Bad Window (invalid Window parameter)"

The environment is Linux - RedHat EL3, Sun Java SDK 1.4.2_07.

Cleaned up some of the disk space and it worked for some time and then started 
crashing again.

Are you using Eclipse over an ssh tunnel?

If so, try using "ssh -Y" instead of "ssh -X", does this make
the problem go away?
Comment 2 Vishnu CLA 2005-11-15 21:30:18 EST 
Yes, I am using ssh tunnel.

I tried the -Y option and it works fine.

Thanks.
Comment 3 Billy Biggs CLA 2005-11-15 21:36:11 EST 
Some history about this problem:

ssh changed to require that by default, X tunnels are subject to tighter
security requirements.  This breaks toolkits such as SWT which send
mouse pointer events relative to the root window, under X servers which
consider this a security violation.  Many other applications also crash
now under -X, so it's not really specific to Eclipse.  I'm not sure if there's
any good fix besides telling people to use -Y.
