Too many of our dependencies do not have real OSGi bundles available, so we have to resort to the spring repository - where the versions almost never match our original target version. Further when it fails it's almost freaking impossible to determine why it fails.

A much shorter repository but with better maintained bundles is the repository of service-mix bundles: http://repo1.maven.org/maven2/org/apache/servicemix/bundles/ which host bundles for service-mix, camel etc.

Please feel free to submit a pull request that moves us to maintained OSGi bundles.

There is an outstanding OSGi pull request for Camel. However I cannot accept the submission until it comes with a unit test. Anyone want to finish that off? Here is the JIRA, pull requests are linked from the JIRA.
https://issues.jboss.org/browse/JBRULES-3389

Here is a sample OSGi unit test:
https://github.com/droolsjbpm/droolsjbpm-build-distribution/blob/master/drools-osgi-bundles/org.drools.osgi.test/src/test/java/org/drools/osgi/integrationtests/SimpleOsgiTest.java

The unit test doesn't need to do much, just show we can build an end point and drive data through it.
