Cannot find a specialized producer on JDK 1.7, it works on JDK 1.6

Suppose there is a specialized producer method (with @Produces and @Specializes annotations) that overrides its superclass's producer method. If you add a method to the superclass, Weld fails to find the overridden producer method on JDK 1.7. The same program works on JDK 1.6.

Here is the stack trace from a test case.
