 |
|
I have a relatively large Applet that runs in the browser, but just recently won't run in applet viewer. (In fact nothing will run, even simple blank applets).
NB 6.8, Jdk 6 U 20, Win XP 2 gig ram.
Error:
java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThreadGroup)
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:323)
at java.security.AccessController.checkPermission(AccessController.java:546)
at java.lang.SecurityManager.checkPermission(SecurityManager.java:532)
at sun.applet.AppletSecurity.checkAccess(AppletSecurity.java:235)
at java.lang.ThreadGroup.checkAccess(ThreadGroup.java:299)
at java.lang.Thread.init(Thread.java:332)
at java.lang.Thread.<init>(Thread.java:391)
at RTSphere.init(RTSphere.java:42)
at sun.applet.AppletPanel.run(AppletPanel.java:424)
at java.lang.Thread.run(Thread.java:619)
Everything used to work fine, then when I got update 20 (around there), not even the simplest applets will run in the viewer. Please help! |

| Code: | import java.applet.Applet;
public class AppletGameCore extends Applet implements Runnable {
private boolean stopped = false
public void init() {
Thread t = new Thread(this);
t.start();
}
public void main() {
}
@Override
public void run() {
while (!stopped) {
try {
Thread.sleep(20);
} catch (InterruptedException ex) {
}
}
}
} |

Somehow:
-Djava.security.policy=applet.policy
Got inserted into my VM options on build. Very odd.
(Properties->Run->VM Options)
Removed it and now it's back to normal... |
