Hi Kevin, all, attached please find a revised patch, where I have added the required export to PlatformImpl and have fixed the build script, so it does no longer break when being executed in jigsaw mode.
As swt is no named module yet, I have disabled the JUnit test in jigsaw mode for now. We would probably have to set up swt as a named module to enable this, and would further have to make swt-debug.jar available as an automated module on its module path. But this is a different problem. Regards, Alexander
