Eclipse 3.2 M3. Open this compilation unit. You will see same exception as below. I agree, that code is mad. :-) Notice, that code has error and this bug can be reproduced only if it has error, if I initialize "button" variable with "null" I will have no exceptions. package apps; import org.eclipse.swt.layout.GridLayout;

I don't have access anymore to 3.2M3. Can you still reproduce with 3.2.1 or 3.3 builds? I could not reproduce in 3.3M2. Closing as REMIND.
I can not reproduce in 3.3M2 too.
Mark as CLOSED then. Thanks for your time.
As of now 'LATER' and 'REMIND' resolutions are no longer supported. Please reopen this bug if it is still valid for you.
