Description

In various cases, core reflection reports incorrect annotation on parameter if the number of parameters in the source code representation and the class file representation differ. Bug JDK-8074977 corrects that behavior for non-static member classes.

The remaining situations should be corrected as well.

Additional correction/update to include from feedback received from jfranck after JDK-8074977 was pushed: http://mail.openjdk.java.net/pipermail/core-libs-dev/2017-May/047944.html Nit: TypeAnnotationParser.java "126 // If a constructor has a mandated outer this, that parameter 127 // has no annotations and the annotations to parameter mapping 128 // should be offset by 1." From memory this comment is a bit misleading since the outer this might actually have a receiver type annotation. The outcome seem correct though.
