--- Comment #8 from Jonny Heggheim hegjon@gmail.com --- (In reply to Per Bothner from comment #4)
I tried running try-fedora-review (see https://pagure.io/FedoraReview) and then installed the resulting rpm.
I then tried building Kawa (https://www.gnu.org/software/kawa/) using /usr/bin/javac - and that failed to find the jfx classes.
As a work-around I created in /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-11.b14.fc27.x86_64/jre/lib/ext a link to /usr/lib/jvm/openjfx/rt/lib/ext/jfxrt.jar . That allowed the compile to succeed. However, the resulting executable failed to run. I didn't continue, but it's plausible that java couldn't find the right shared libraries.
Since openjdk is installed in a versioned directory (with a nest of alternatives links), we have to install openjfx using a compatible layout.
There have been a long discussion at bug 1145303, where the plan is to have two packages, this one with the binaries and another with the symbolic links that is part of an openjdk sub-package.
It would be great if you can test Kawa by following the steps described in /usr/share/doc/openjfx/README.fedora
