May I please have reviews for this trivial patch? On Linux, I get compiler warnings when building the jspawnhelper. It complains about not checking the return code to write when communicating an error code back to be parent.
I decided to just fix it since this is indeed a bug. But there is no real way to produce error output since stdout/err are redirected. So I decided to just exit with a clear error code instead. bug: https://bugs.openjdk.java.net/browse/JDK-8213017 cr: http://cr.openjdk.java.net/~stuefe/webrevs/8213017-jspawnhelper-write-return- code/webrev_0/webrev/ Thanks, Thomas
