Support annotations on parameterized types
It appears that java.validation allows validation annotations to be used on the type parameters of Collection and Map classes. Updated the validation code to support that. Once policy-models has been updated to use this approach, the original @Items and @Entries annotations will be deprecated. Issue-ID: POLICY-2648 Change-Id: Ic953be485ebafc9869f72407518f6549585353c9 Signed-off-by: Jim Hahn <jrh3@att.com>
