FINALLY!
We were able to fix the problem :)
First of all we migrated to 1.5.0
Then we noticed that the exception I mentioned in my last post was caused by
some jar files in the target folder, namely:
appengine-api-labs
appengine-api-stubs
appengine-testing
So we excluded those jars from being compiled into the target folder (we
only need them for local unit testing.)
After this steps were made the channel was finally working.
Moishe, thanks for your help :)
Kind regards,
Z
