About Question enthuware.ocajp.i.v8.2.1385 :

[admin]

It is not about whether the exception in the catch block is same or not. You need to see if the exception thrown in the try block satisfies the "is-a" test with respect to the exception class mentioned in the catch block.
For example, in this case, you need to see whether an instance of ArrayIndexOutOfBoundsException is-a MySpecialException? No. So an instance of ArrayIndexOutOfBoundsException cannot be caught by MySpecialException.

If the code in the try block threw an instance of a subclass of of MySpecialException, then it would have been caught by the given catch block.
