Andrew Block commented on CAMEL-8185:
-------------------------------------
Tested using both Karaf 2.4 and Fuse 6.1.1 (redhat-611412) using the
camel-archetype-scr with a similar configuration as described in this issue.
Successfully deployed to Karaf but threw identical exception in Fuse.
Diagnosed issue to be a potential class loading issue with SCR using bind
methods from an abstract class. When overriding methods in subclass and calling
super, context deployed successfully on both Fuse and Karaf without error.
