> The ServiceCache introduce with SLING-1478 is prone to deadlocks with the
> Framework.
> The serviceChanged method is called from the framework and tries to
> synchronize on the cache. The getService method on the other hand
> synchronizes on the cache and while holding the lock calls into the framework.
> The fix is to not hold a lock while calling into the framework.
