What is your comment about the following codes ?
try {
    try {
        throw new Exception("E_0"); // Exception_0
    }
    finally {
        int i = 5;
        i /= 0; // Exception_1
    }
}
catch (Exception e) {
    e.printStackTrace();
}

My first comment is that printStackTrace is not an acceptable exception
handling problem (it really should have "debug" in its name).

My second comment is that the exception from finally should be at least
as significant as the first exception. There shouldn't be much happening
in the finally block. Now, you've switched to a made up example, but the
original, writing to a stream, is common. In that case, if you can't
even close the file you have real problems - at least as bad as not
being able to write to it.

The "code_1" above prints both "Exception_0" and "Exception_1".

So is that going to be two dialog boxes with cryptic and entirely
unhelpful messages? ;)
