Description

Enabling the Jackson type converter causes trying to convert from a String to Enum to fail. I fixed my offending code for this to set an enum constant on the header but I would have not expected this to happen.  I suggest checking if the class type is an enum in JacksonTypeConverters and returning null so that a fallback converter can be used instead.
