Description of problem:

this following issue is nice to have and not sure if have any production implications; but maybe solved with correct jboss configuration, flow and impact are pretty obvious: 

- jboss running engine is running 
- refresh git repo 
- run mvn with deploy param 
- do not stop jboss 
- re-login to webadmin; everything looks usual and working
- activate host

host is stuck on unassigned state while engine log producing the following exception:
