    This is a drop in replacement for the auth0 java-jwt library (see https://github.com/auth0/java-jwt). This jar makes sure there are no external dependencies (e.g. fasterXml, Apacha Commons) needed. This is useful when deploying to an application server (e.g. tomcat with Alfreso or Pega).

/**
 * Simple implementation {@link Deserializers} which allows registration of
 * deserializers based on raw (type erased class).
 * It can work well for basic bean and scalar type deserializers, but is not
 * a good fit for handling generic types (like {@link Map}s and {@link Collection}s
 * or array types).
 *
    
 * Unlike {@link SimpleSerializers}, this class does not currently support generic mappings;
 * all mappings must be to exact declared deserialization type.
