Right, the `loadLibraryOnlyIfPresent` change is sufficient for `System.load("libname.a(member)")` support. I don't know how common ".a" without member specification ist, but that may make sense. It sounds similar to what was done for MacOS with https://github.com/openjdk/jdk/commit/1e4dfcfbf00a9b17418bccc0dc746fd9a71f3a06.
