neverending connection on pull

[jwierzbo]

Took me a lot of time to tracked this bug. Here we go:

I used threads to pull from specific queue and all the time, after some random time, my pullers stopped working accidentally. I thought that was the problem with pool thread in Java, but I was wrong. In thread dump I've seen that all my pulling-threads are stuck in same line of code - IronMqJava library Client.java:

int status = conn.getResponseCode();

In above code we make request to ironMq server, but we haven't set timeout param which by default is 0 - inifinty. So if an error happen on IronMq server our code is waiting for the response forever!

That's why I added following lines:

conn.setConnectTimeout(this.httpTimeout);
conn.setReadTimeout(this.httpTimeout);

After this now I get familiar error:

I'm using forked code so I couldn't prepare fix straight.

Why has there not been any progress/response on this bug ?

BTW above issue refers to IronMq V3 - I haven't check it with V1
