Description

IN SerializedExceptionPBImpl deserialize() method

    Class classType = null;
    if (YarnException.class.isAssignableFrom(realClass)) {
      classType = YarnException.class;
    } else if (IOException.class.isAssignableFrom(realClass)) {
      classType = IOException.class;
    } else if (RuntimeException.class.isAssignableFrom(realClass)) {
      classType = RuntimeException.class;
    } else {
      classType = Exception.class;
    }
    return instantiateException(realClass.asSubclass(classType), getMessage(),
      cause == null ? null : cause.deSerialize());
  }

if realClass is a subclass of java.lang.Error deSerialize() throws ClassCastException.
in the last else statement classType should be equal to Trowable.class instead of Exception.class.
