I used the full version of jdk 14.0.1 on Raspberry Pi where JavaFX is included in jdk so the file _javafx.platform.properties_ is already in jdk-14.0.1-full/lib directory. To debug the JavaFX on Raspberry Pi I built armv6hf-sdk and just copied the file _javafx.platform.properties_ from the full jdk version with JavaFX to jdk-14.0.1/lib directory of jdk without JavaFX which I used to run my java application with JavaFX modules from armv6hf-sdk/lib. ------------- PR: https://git.openjdk.java.net/jfx/pull/193
