Remi,
The other reason to have read that returns 0 is if the underlying channel is in
non-blocking mode.
A read on an InputStream created by Channels.newInputStream on a
SelectableChannel may return 0
and the code will go in a loop until the SelectableChannel can read something.
while(read() > 0) avoid that issue.
It doesn't seem possible as far as I can see. We have 2 methods in
java.nio.channels.Channels:
newInputStream(java.nio.channels.ReadableByteChannel)
newInputStream(java.nio.channels.AsynchronousByteChannel)
Neither ReadableByteChannel nor AsynchronousByteChannel is SelectableChannel.
SocketChannel is a subtype of both ReadableByteChannel and
SelectableChannel.
Sorry, I might be missing something. Anyway, it would be a misbehaving
InputStream as it doesn't conform to the spec.
if the read is non-blocking, it can read 0 byte which is conform to the
InputStream.read spec,
or am i missing something ?
