Realized I only sent this to Claus before:
Yeah that worked. so now my route looks like:
from("jms:topic:heartBeatWithCounts?connectionFactory=#javax.jms.ConnectionFactory")
Yeah that is the problem with having osgi services for this is that multiple
ones can be used. The way I believe to fix that is to set the service ranking
higher on the service we really want, but still a problem.

You can use the # notation in the endpoint uri to lookup any bean from
the registry with the given id.
?connectionFactory=#myFactory
But it must have a name to lookup? It cannot lookup by type and just
pick the first one?
We could of course add such a feature, and have a convention if there
is exactly only 1 of the given type, then use that. If 2+ then throw
an ambiguous error.
There is a lookupByType API on the registry we can leverage for that.
Although we may need some convention so when you use # it will lookup
by id first, and then fallback by type. Or we can introduce a syntax
to indicate by type, such as: #!
The downside when doing this is that you rely on there only being
excactly 1 type in the registry. And with OSGi things can be hot
deployed, so what happens if some other bundle registers 1 new JMS
connection factory. Now there is 2 in the osgi service registry. And
then you may restart your bundle, and when it startup again it detects
2 JMS connection factories, and fail to start.
