Description

Enum types should be supported in GenericData.deepCopy() so that we can convert from (in memory) generics records to specifics records.
Without this fix in place, it is non-trivial to attempt to create specific records from generic records if they may happen to have any nested enum data types.

This issue has already been pointed out by Doug Cutting which can be referenced at [1] and [2].
In [2] specifically, Doug proposed the change that would fix this issue.
