Log Message: |
FELIX-4561 - Unregistration fails sometimes:
- if the HttpService itself is stopping, it deregisters all of its
servlets and filters. This causes the whiteboard service to also
start deregistering its servlets & filters, causing exceptions in
the HttpService;
- make the whiteboard unregister at best-effort, catching exceptions
that occur during the unregistration & log a message instead;
- suppress throwing of exceptions when unregister is called on the
HttpService while the bundle is stopping.
