Hi Julian,
Ok ... I think with "disable" you are referring to "comment out the MBean
stuff" in the TiggeredScraperImpl class?
Cause other than that, I can't really see a "switch" to flick.

Hi,
I'd rather disable MBean support (I'm unsure if someone uses it currently)
then to rename these classes.
They are part of the exernal API and e.g. used by us (and probably others)
which makes the change incompatible which I would avoid for upcoming release
0.5.

If we name the class "TriggeredScraperImplMBean", the interface has to
be
renamed to "TriggeredScraperImplMBeanMBean".
class *X* -> interface *X*MBean
