Surprisingly this is another example of slowdown when loading default resource via our classloaders. Just find:
org.apache.commons.logging.LogFactory$4.run()
the rest of the system waits for this load to finish.

I am making this P2, as I know this is at least 10th duplicate of such problem. We need to improve classloading from default package, to not open all JAR files.
