[rabbitmq-discuss] Strange behavior when accessing properties of a delivered message (in Java)

Wed Aug 11 16:16:43 BST 2010

Thanks for the quick reply!  Turns out someone wrote the equivalent of this
in a class I was using:

while (true) {
  try {
    // get next delivery
    // process next delivery
  } catch (Exception e) {
    continue;
  }
}

:thinking:

Thanks for your help!
