JPA connector pooling doesn't appear to shutdown

Our integration tests now appear to be running forever in what appears to be an infinite loop. The unit tests in 'docs/examples/gettingstarted/repositories' module appear to run forever, with the log ending with the snippet below (which goes on forever). Note that the example is running with DEBUG (which also needs to be changed).
