Hi Wang, Apologies. There is a bug in the the JDKLoggingImplementationPolicyProvider. We must be using component.getPolicySets() and not getApplicablePolicySets(). I am in the course of fixing this along with a few other things in the branch for our 1.2 release after which I will syncing up the trunk for this. So in about an couple of hours you should see all of this working from the trunk as well.
There is one thing that I noted though in your definitions.xml. It seems to be providing the 'implementationType' definitions for the sca: implementation.java extension. You should not be doing this as this is something which should be a part of implementation.java extension itself. The trouble that this can cause is with the intents that you might specify as 'mayProvides' and 'alwaysProvides'. When you use the intents defined under these, in your composite, they will never get matched with policysets because, for these it is understood that the extension itself handles what needs to be done.
