Thanks for the discussion and reviews @robehn  and @tstuefe 

> But setting a SIGPIPE handler - or temporarily disabling it - without signal chaining seems to be such a common pattern that we now remove the warning instead. We basically throw the hands in the air and give up.

Given changing the handler is somewhat expected/normal then issuing an alarming warning only annoys people who expect to be able to run JNI-warning free.
