Cannot map a field value to an enum value if value is a keyword

What steps will reproduce the problem?
1. For a json object { visibility : "public" }
2. Create an enum with a value of public.
eg: enum Visibility { PUBLIC, PRIVATE }
3. Create a member variable private Visibility visibility;
4. Run your fromJson(...)

Other parsers allow you to use the toString or name methods of an enum to 
determine value instead of calling valueOf(String) as a builder config.  This 
would be great.

What is the expected output? What do you see instead?
Parse exception.
