JFXPanel security exception

Question

I updated to 1.7.0_67-b01 and now it seems I can't embed a JavaFX panel in my swing application. This is the exception I get. Anyone knows a workaround?

java.security.AccessControlException: access denied ("java.util.PropertyPermission" "javafx.macosx.embedded" "write")

Is it ordinary application, jnlp or applet? – Dmitry Ginzburg Aug 05 '14 at 11:10 — Dmitry Ginzburg, Aug 05 '14 at 11:10

You should modify your policy file ($JAVA_HOME/jre/lib/security/javaws.policy) to include permissions to write this property. So, you should add this line to javaws.policy:

permission java.util.PropertyPermission "javafx.macosx.embedded", "write";

It seems to be the old bug

But I don't need a policy file. The application is signed. Also how would I force all the users to modify their policy file? – Spiff Aug 05 '14 at 14:04
I checked the bug, Oracle says that this is not a issue! Although the bug is old this occurs only with update 67. With 65 it works. – Spiff Aug 05 '14 at 14:36
Then I have to ask on how do you deploy your application. I would recommend just using "javafxpackager -deploy". – Dmitry Ginzburg Aug 06 '14 at 10:16
It's a swing application. The user has just to hit the jnlp, and Javaws would take care the rest. By the way I tested Java 8 Update 20, and it works also, no issue. It's not a bug according oracle, so oracle never fixed and never will, and yet the error occurs in some java versions! – Spiff Aug 06 '14 at 13:18
That's okay, javafxpackager creates jnlp too – Dmitry Ginzburg Aug 06 '14 at 13:27

I tried what's suggested in this post and it works.

I add the permission programmatically.

PropertyPermission propertyPermission = new PropertyPermission("javafx.macosx.embedded", "write");

However the permissions of the orginal policy are lost.
