   * A base class for logical types that are not understood by the Java SDK.
   *
   * <p>Unknown logical types are passed through and treated like their Base type in the Java SDK.
   *
   * <p>Java transforms and JVM runners should take care when processing these types as they may have
   * a particular semantic meaning in the context that created them. For example, consider an
   * enumerated type backed by a primitive {@class FieldType.INT8}. A Java transform can clearly pass
   * through this value and pass it back to a context that understands it, but that transform should
   * not blindly perform arithmetic on this type.
