The changes in awt_LoadLibrary.c and XToolkit.c is mostly noop except excluding dladdr/dlopen. Since XsessionWMcommand/AWTIsHeadless are not used at least in the mainline(jdk16). The changes in the mlib look fine. The testing is in progress. ------------- PR: https://git.openjdk.java.net/jdk/pull/562
