Description

When I switch my karaf trunk snapshot from jdk 6 update 31 to update 33 all karaf commands stop working.
I was able to track this down to blueprint and the proxy facility or aries.

The exception I get is:
org.osgi.framework.ServiceException: Service factory exception: (class: org/apache/karaf/shell/console/commands/$BlueprintCommand16496117, method: <init> signature: (Ljava/lang/reflect/InvocationHandler;)V) Call to wrong initialization method

In the log this does not show. There I only get a Nullpointer exception as the service object for the command is returned as null.

I have documented more details in the linked karaf issue.
