Blueprint: not ignoring already created

[Bradford Fisher <br...@bradfordfisher.com>]

I'm trying to use a blueprint.xml to initialize my camel routes. From the Camel
Spring Documentation <http://camel.apache.org/spring.html> it looks like
the <package> tag is supposed to ignore any pre-existing route builders
created through the use of the <bean> tag. However, it looks like Camel is
still trying to initialize a new instance of the DirectTestEndpoint.

If I remove the <package> tag, leaving on the <contextScan> tag, everything
works as expected and the DirectTestEndpoint is created with the action.

Is behavior expected with OSGI Blueprint descriptors, or am I doing
something incorrectly?

Thanks in advance!
