This is an OpenJDK 9 build. Can you explain? I'm very interested in getting all the details understood. Hey thanks!

What is the issue here? Which JDK build is this? I can't tell if it has the map files used by the linker (mapfile-vers in the case of libjava) or not. The map files don't exist in the main line but they may exist if you are working on a patch for a previous release.
