Hello
Somehow I thought you're using Pax Web 8 which actually has working context
selection. Problems with context registration/selection were the MAIN
reason I started refactoring of Pax Web 7 into Pax Web 8.
Your example is _canonical_ example of Whiteboard usage and should work
perfectly fine with Pax Web 8 (included in Karaf 4.4.3).
regards
