Subject Re: Getting closer with Java7....
Date Tue, 08 May 2012 07:42:18 GMT
I have created a Java 7 compliant osgi spec bundle in Karaf.

So if we need the generics we could use this. As the module is basically 
just a pom we could also simply do the same in camel to avoid
the additional dependency.
