Could you also please take a look of the changes that excludes the object files from the following static libraries from Graal native image usage perspective? - For libjli.a: Not include inflate.o inftrees.o inffast.o zadler32.o zcrc32.o zutil.o (compiled from zlib sources) if zlib is built as JDK bundled. - For libawt_xawt.a and libawt_head.a: Not include systemScale.o, since it's provided in libawt.a. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/13768#discussion_r1185436692
