             Summary: MapperException is thrown when deserializing a customized Enum type
                 Key: JOHNZON-112
             Project: Johnzon
          Issue Type: Bug
          Components: Mapper
    Affects Versions: 1.0.0
            Reporter: Steven Walters

* Customized Enum type that has an alternate naming scheme than typical java
* Custom Adapter between custom Enum type and String to use in serialization/deserialization

Mapper configured to use adapter uses adapter for both serialization and deserialization operations.

Mapper uses configured adapter for serialization, but uses Enum.valueOf for deserialization,
throwing Exceptions on its use.

Root Cause Analysis:
It seems that in MappingParserImpl.convertTo(final Type aClass, final String text)
The custom adapter is attained successfully, but is ignored because "valueOf" method exists
with public static modifiers.

Seems like if the adapter exists, it should be used, only using valueOf as a fallback when
it does not...

Attaching minimal maven project that reproduces problem with "mvn test"
