PROBLEM

Annotation with target TYPE_USE seems to be copied to bridge methods. As bridge methods
only delegate back to the overloaded method, these annotations are typically invalid.
The reproducer shows that the type annotations specifies a PC range which is longer
than the byte code of the method.
 
Probably type annotations shouldn't be copied to bridge methods.
