-------------------------------------------
Hi Steffen
The trouble here is that it is difficult to say what the default value should
be, as it may not suit all types of HTTP service handlers. In some cases where
the size of the content buffer stays constant, it makes sense to have a largish
value. For expandable buffers it would probably make make more sense to keep
the initial size relatively small. I think this is more of a problem with the
silly practice on the part of SUN developers to throw generic exceptions
without an accompanying message that describes the nature of the problem.
What the default value should be?
