[WARN] Could not instantiate listener

I recently updated my app to use GWT 2.2 and AppEngine 1.42
GIN 1.5 and GUICE 2.0.

Prior to this I was using 2.1.1 and Gin 1.0 and Guice 2.0 with no
issues.

After the update the following error appears...

[WARN] Could not instantiate listener

and I cannot figure out what is wrong.
I have another app saved form back in 12/10 that uses
the same infrastructure and format (except 2.1 and gn 2.0)
When I fired it up I set it to use GWT 2.2 and AppEndine 1.42
Gin 1.5 an guice 2.0. and It works ...

Believe me! nothing is different between the two app from the
point of view of code.

Here is thstack trace
