Description

Usually people will write code around consumer like

while(iter.hasNext()) {
try {
msg = iter.next()
// do something
}
catch{
}
}

---

However, the iter.hasNext() call itself can throw exceptions due to decoding failures. It would be better to move the decoding to the next function call.
