Hi, so here's a reworked version of my previous change:
http://cr.openjdk.java.net/~simonis/webrevs/2018/8214120/ https://bugs.openjdk.java.net/browse/JDK-8214120 In addition to my initial change (which unfortunately broke the Solaris build) the new version has to JNIEXPORT the following methods from libawt.so otherwise they won't be visible in libawt_xawt.so on some platforms which make symbols local by default (e.g. Solaris): DAssert_Impl DTrace_PrintFunction DTrace_VPrint DTrace_VPrintln Local tests on Linux/AIX and Solaris succeeded. The patch is currently building in the submit repo. Thank you and best regards, Volker
