Hello, I have a JavaFX Application that runs fine. When I package it as an Applet (three cheers for javafxpackager!), and give that Applet "All Permissions", the Applet throws exceptions and fails to start.
One difference is in fields initialized by FXMLLoader. When those fields have default accessibility they are initialized in the Application but not in the Applet. When those fields are changed to public accessibility, then they are initialized in both the Application and the Applet as well. Given the extra build & debug complexity with Applets, I did an experiment. I tried running the Application with a SecurityManager that approves (doesn't throw an exception for) all checkPermission() calls. Bingo! Similar failures. Now I have a number of questions: 1) How does JavaFX code behave differently when run as an Application with no Security Manager and as an Applet given 'All Permissions'? 2) How does JavaFX code behave differently when run as an Application with no Security Manager and as an Application with a Security Manager whose checkPermission() methods never throw an exception? 3) How does JavaFX code behave differently when run as an Application with a Security Manager whose checkPermission() methods never throw an exception and as an Applet given 'All Permissions'? 4) Why does an Application behave differently when run as an Application with no Security Manager and as an Application with a Security Manager whose checkPermission() methods never throw an exception? I find that difference surprising (but not shocking). 5) Is any of this documented anywhere? I would rather not have to map the minefield myself. 6) Are differences like this documented for the non-JavaFX parts of Java?
