commit ab83dcd6fee848cb0a82a9da328e114cc9e3568b
Author: Matthew McMahon <ma...@gmail.com>
AuthorDate: Tue May 26 23:53:36 2020 +1000

    AVRO-2836 Generated java includes logical type conversions (#883)
    
    * AVRO-2836 Generated java includes logical type conversions
    
    If the logical type is used for a Fixed type (potentially also Enum)
    then it should check if there are any conversions used, and
    include in the generated java source
    
    * AVRO-2836 Generated java includes logical type conversions
    
    Move enum and fixed to use the javatype method, as if there is a
    logical type conversion it will be picked up and remove a
    code path
