Hi,

We are using C3P0 datasource with Hibernate in SPRING framework.
When we start the server, the startup process ends abruptly. We can see following stack trace in the log file. Is anyone having info what can cause this problem?

Hm, seems c3p0 is trying to register jmx mbean. Try to disable the jmx registration, or maybe your are missing some classes on classpath.

See NullManagementCoordinator there.
