Description

After upgrading from Camel 2.6.0 to 2.8.0 we got a regression in one of our unit tests (I attached a simplified project which show the defect). This regression still exists in Camel 2.11-SNAPSHOT.

I think this regression was introduced by myself with the following commit:

    CAMEL-4120: camel-sql - JDBC aggregation repository - Should use ClassResolver from Camel to load classes
    
    git-svn-id: https://svn.apache.org/repos/asf/camel/trunk@1137802 13f79535-47bb-0310-9956-ffa450edef68

This is the exception I receive:

And as I said, everything works with Camel 2.6.0.
