A quick question, is your customer bundle status is "Active"? And there's no any exception even in the log?
Yes, the status is active and there are no messages, errors or otherwise.
In the meantime, I was able to get the bundle running inside eclipse and the start method is being called and the bundle registered as a managed service. Interesting that the same bundle has different behavior running in Fuse ESB and an OSGI Framework run configuration in eclipse...
I just did an uninstall and clean install of bundle and it now registering as a managed service with start being called. Not sure if it is because I did a fresh install rather than an update (even though I check the header it the bundle appeared to be updated) or because I changed the pom file slightly to use maven-scr-plugin:
