JMX beans registrations for each pool is not unregistered while closing the pool.
I still see the beans named like this:
the com.mchange.v2.c3p0:type=C3P0Registry is unregistered.
Used to work in 0.9.1.2 version
0.9.5-pre4 and 0.9.2.1 producing the problem.
JVM: Oracle 1.7.0_25
ComboPooledDataSource is used
((ComboPooledDataSource) dataSource).close(); called when web application is stopped.
