Sure .. we updated the test to ignore these warnings ... but I was hoping that maybe your changes would obsolete the need to ignore them. However I actually suspect it won't help if it just minimises them rather than eliminates them. It stems from the GTK library (the standard library for Gnome desktop apps on Linux) calling (SIGPIPE, SIG_IGN) during initialization Their reasons are here : https://docs.gtk.org/gtk3/func.init.html So the VM warnings are something of a mild annoyance that we've worked around in this test but it never made sense to me what this has to do with JNI ? ------------- PR: https://git.openjdk.org/jdk/pull/9631
