As you can see, when there is no data available it just returns an
emty string.
I would check in.remaining() before reading the header
Thanks for your help. As you may see this test is already done in
decodable(). As far as I know decodable is called before decode. So when
readHeader is called there is more than HEADER_LENGHT data? So an empty
string is not return. By the way, let's imagine that it is the case, I
don"t see how it can be related to a duplicate message ? again do i miss
something important ?
