[ARIES-1979] NPE while refreshing chain

Description

I get a NullPointerException when registering some chain filters or endpoints. I could trace the problem back to the refresh() method of ServiceTuple. After the AtomicReference _service is set to null and before the new value is set later on, a call to getService() occurs in another thread which causes the NPE.

This leads to the problem that a filter in my chain filter is being skipped sometimes while the my application starts which causes bugs.

 

P.S. I had to change the code a bit to get the stack trace. It seems the logging in Whiteboard:895 can be improved a bit to log stack traces.
