We know this error, and we have seen this in every installation we have 
here, every time we shutdown tomcat.

Since this is a very generic error and it doesn't have any impact on our 
DBs, we haven't fixed it.

This is very weird, if opal2 starts properly it must print some log, on 
my installation I could get some ClassNotFound errors when trying to 
restart a stopped application from the manager interface.

Right now Im out of town when I will be back I'll take a look at this 
problem.


Sincerely,
Luca
