What Piotr describes is sadly the kind of insane setup one must have to work with JPMS and keeps me saying JPMS is something to work around, not work with. I plan on keeping using hacks like the Moditect plug-in and whatever I have to in my apps to avoid JPMS. What I really want is a --jpms-off toolchain switch...
