I decided to try and figure out where the empty source path regression was coming from, and possibly fix it. See: http://mail.openjdk.java.net/pipermail/jigsaw-dev/2017-June/012938.html
But, when I checked out the sources from mercurial and tried to build them, I ended up getting some errors. Anyone know whether I should be suspecting my development environment or the actual code? Here's what I did based on these instructions. http://hg.openjdk.java.net/jdk9/jdk9/file/023f93e511ba/common/doc/building.md $> hg clone http://hg.openjdk.java.net/jdk9/jdk9 openJDK $> cd openJDK $> bash ./get_source.sh $> bash ./configure --with-boot-jdk=$JAVA_HOME Output here: https://drive.google.com/file/d/0Byp8Kl9b7wdibzk2TEFzN3ExVXc/view $> make clean $> make all LOG=debug Output here: https://drive.google.com/file/d/0Byp8Kl9b7wdiSEpVeHNjSDBIZTA/view Any help is appreciated. I *think* I have installed the prerequisites according to the instructions although my version of XCode (8.3.3) is considerably newer. It wasn't clear of XCode 6.3 was a minimum requirement or an exact requirement. Thanks, Pepper
