I wrote it to debug a failure to connect so this was never a concern - the JVM exited right after this. It was NOT intended to be used how you are using it. It is intended to debug configuration issues.
Closing this connection is non-trivial.
For what I think this is doing, you would be better off making a simple fetch
of an entity that you know is there.
