Subject Re: DO NOT REPLY [Bug 19868] - Need the InterruptedIOException when timeout
Date Wed, 14 May 2003 20:20:20 GMT
I agree it does seem to be an overkill in this particular case. But I
personally find the flexibility offered by chained exceptions worth
paying the price. This might wait until 2.1, though.

You are absolutely right about the overall concept of exception
handling  getting a bit vague. There used to be a pretty clear
convention before with HttpException representing protocol errors and
IOException representing transport errors. It got lost somehow. 

I think we do not have to invent much. We just have to be a bit more
stringent about respecting the convention that has already been
established. 

Cheers

Oleg
