> There is a JMX registration issue in TestBasicManagedDataSource.
> If the test is run with logging:
> mvn test -Dtest=TestBasicManagedDataSource -Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.SimpleLog
> then lots of stack traces are shown as below.
> This appears to be because each name can only be registered once.
> Perhaps the test is flawed, and it should deregister the name in tearDown() ?
> However there does not seem to be a way to deregister the name.
