-------------------------------------------------------------
Note this can lead to NPEs in ProducerPropertiesFilter since the resource isn't
set. I assume that it is not a heavily used feature (I need it for SLA
enforcement on metrics etc), if people need a simple workaround for 2.2.0 (just
the ProducerPropertiesFilter issue) feel free to email me.
As a long term solution it may be better to introduce a
processProducer(NotificationProducer) function into the Filters. TopicFilter
can use it directly, and ProducerProperties can use it to call getWsResource().
That would do away with the instanceofs. This would allow further handling to
be pluggable with the FilterFactory handlers rather than new releases or
deriving from ProducerPropertiesFilter

> Any subsciption that is made remotely (e.g. via subscribe method on a proxy)

> subscriptions).
