Could you please also revive the UserJvmOptionsService, that (for very unclear reasons) was removed together with JavaFX?
Since the functionality provided by the UserJvmOptionsService requires some cooperation with the launcher created by jpackage, I can't see how I could implement some work-around myself. (I raised this question already in https://mail.openjdk.java.net/pipermail/core-libs-dev/2019-March/059419.html, but without response.) Best regards, Lennart Börjeson
