This is merely an observation of a weird behaviour rather than a functional bug per se. Workers listening to proxy advertisements simply ignore the byte gibberish, so there is no disruption of service. On the other hand, Apache HTTP Server advertisements has never, to my best knowledge, produced anything like this on Linux ~ 3.19.5 OS. The following log was produced with famous ancient test utility Advertize.java.

Until I found out more about or spot any evil side effects, I shall keep the Priority on Minor.
