From what I understand of the problem, it will go away once you recompile from 
source. The bytecode is incompatible.

No, it will not. Current java code of gwt-comet is not compatible with GWT-2.2.

It seems to work for me after making the changes in attached patch.  The patch 
is against r159 (1.2.1).  Hope it helps.

Hello

How do I get this patch?  I just checked out from 
http://gwt-comet.googlecode.com/svn/trunk and don't see any updates since 
1/4/11.
Also I downloaded the latest 1.2.1 jar and still seeing the issue.

Thanks
