I think we should separate this issue as following: * Suppress warnings * make/modules/java.desktop/lib/Awt2dLibraries.gmk * src/hotspot/share/classfile/bytecodeAssembler.cpp * src/hotspot/share/classfile/classFileParser.cpp * src/hotspot/share/jfr/recorder/checkpoint/types/traceid/jfrTraceIdBits.inline.hpp * src/hotspot/share/opto/memnode.cpp * src/hotspot/share/opto/type.cpp * src/hotspot/share/utilities/compilerWarnings.hpp * src/hotspot/share/utilities/compilerWarnings_gcc.hpp * src/java.base/unix/native/libjli/java_md_common.c * Bug fixes * src/java.base/share/native/libjli/java.c * src/java.base/share/native/libjli/parse_manifest.c * src/jdk.jpackage/linux/native/applauncher/LinuxPackage.c I want to include the change of Awt2dLibraries.gmk (HarfBuzz) in this PR because it is 3rd party library. I will separate in above if I do not hear any objections, and this issue (PR) handles "suppress warnings" only. - PR: https://git.openjdk.java.net/jdk/pull/8646
