> Erroneous BPEL process deployment caused NullPointerException in DeploymentPoller and
poller is exited after that, no possible deployments possible after that.

an unexpected error.  Exiting poller...

>         ... 4 more
> Workaround:
> 1. Stop Tomcat
> 2. Delete erroneous process
> 3. Start Tomcat
> Attached the erroneous process (first version) which caused that problem and good version
which can not be deployed after that. We need to perform procedures above and then deploy
good version to get it working.
> Just stopping and starting Tomcat doesn't work - once started again the same NullPointerException
seen and poller exits, no further deployments possible..
