The type annotations on a cast are not reflected in the output of javap unless the cast
is annotated with more the one annotation types. Repeating the same annotation is not
enough, however, two annotations with different retention policy is enough.

To reproduce, compile the following class and run javap, and observe the lack of
CAST type annotation for the fiels "not_ok".

Note: I'm filing the problem against javap, as it was uncovered in javap testing.
It' is likely, however, that the problem is at the classfile level.
