But the exception parameter t is declared as a Throwable, and Throwable cannot be thrown from foo unless the throws clause is modified.

但是异常参数t被声明为Throwable，且如果没有修改throws子句，则Throwable不能从foo中抛出。

Also note that the invoke method declares that it throws Throwable, so you either must catch it or let your testing framework handle it, as I've done.

还请注意invoke方法声明它要throws Throwable，必须捕获异常或者让测试框架处理它，就像我做的那样。
