We are compiling of course with Java 8 compatibility (Lucene is on Java 8). My question was more, how it works now. If the aggregator module is gone, how does javac figure out the profiles?

Maybe it is because we use --release 8, if it detects a Java 9 compiler (some handmade Ant logic does this for us) instead of -source/-target ( In that case it uses the old version in ct.sym file for compiling, right? But how does it work with -source/-target?
