getMessage

public java.lang.String getMessage()
You can also modify the body of this method to customize your error messages. For example, cases like LOOP_DETECTED and INVALID_LEXICAL_STATE are not of end-users concern, so you can return something like : "Internal Error : Please file a bug report .... " from this method for such cases in the release version of your parser.
