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..
