IllegalArgumentException: object is not an instance of declaring class
提问by Jaka Jan?ar
How is it possible that the "foo" exception is notthrown, but a subsequent call of invoke() throws the below exception?
怎么可能没有抛出“foo”异常，但随后调用 invoke() 会抛出以下异常？
if (method.getDeclaringClass() != object.getClass())
throw new RuntimeException("foo");
method.invoke(object);
Thrown exception:
抛出异常：
java.lang.IllegalArgumentException: object is not an instance of declaring class
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

Beh... The method.invoke()call wasn't the one throwing directly. The target method was using invoketoo and it threw, so it bubbled up.
Beh...method.invoke()电话不是直接扔的。目标法也用invoke了，扔了，就冒泡了。
Lesson learned: Handle InvocationTargetExceptionseparately from other exceptions.
经验教训：InvocationTargetException与其他异常分开处理。
