May I then suggest one additional change to this pull request? It's a two-line fix:

--- a/modules/javafx.base/src/main/java/com/sun/javafx/PlatformUtil.java
+++ b/modules/javafx.base/src/main/java/com/sun/javafx/PlatformUtil.java
@@ -238,8 +238,7 @@ public class PlatformUtil {
             // Strip everything after the last "/" or "" to get rid of the jar filename
             int lastIndexOfSlash = Math.max(
                     s.lastIndexOf('/'), s.lastIndexOf('\'));
-            return new File(new URL(s.substring(0, lastIndexOfSlash + 1)).getPath())
-                    .getParentFile();
+            return new File(new URL(s.substring(0, lastIndexOfSlash + 1)).getPath());
         } catch (MalformedURLException e) {
             return null;

That change corrects the code to look for the `javafx.platform.properties` file in the same directory as the
`javafx.base.jar` file instead of looking for it in the parent directory of the JAR file. I just stepped through the
code with this change, and the method `PlatformUtil.loadProperties` now finds the properties file in the location where
it is packaged by the build in the SDK.
