> The GarbageCollector installs an ObservationListener to ensure moved nodes are scanned
as well.
> If there is an exception in the ObservationListener, this exception is captured (lastException),
but only evaluated at the very end of the GC cycle, in Listener.stop() / GarbageCollector.stopScan()
which is called as part of sweep(), before deleting unused items.
> This is quite late. For a large repository, scanning might take a few hours.
> If such an exception occurs, scanning should stop within a reasonable time (fail fast),
and the exception should be thrown there.
> This is related to JCR-3340
