          public static Class<? extends Throwable> findClosestMatch(Collection<Class<? extends Throwable>> exceptionTypes,
                                                                    Throwable targetException)

      Obtain the closest match from the given exception types for the given target exception.
      参数:
        `exceptionTypes` - the collection of exception types
        `targetException` - the target exception to find a match for
      返回:
        the closest matching exception type from the given collection
