Looks like your application installs a SecurityManager and triggers a bug in javax.swing.UIManager.maybeInitialize. I guess there is some call to java.security.AccessController.doPrivileged() missing as java.awt is surely no prohibited package. It should be loaded by the system classloader. If thats not the case, its another bug.
Thank you for this quick answer. No, I don't play with any security aspect. The line "631" of my code at baruchel.hemicycle.Hemicycle.main (Hemicycle.java:631) only contains splash.show();
It is for a splash window appearing on the screen in order to make the user happy
during the launch/initialization time. It is obviously the first window appearing
on the screen.
Since the problem occurs at the very beginning of the execution, I can copy these
lines :
public static void main(String[] args) {
// Splash Screen
JWindow splash = new JWindow();
JLabel content = new JLabel(new ImageIcon(
myClassLoader.getResource(
"baruchel/hemicycle/icons/hemicycle.png")));
splash.getContentPane().add(content);
splash.getContentPane().setBackground(Color.white);
content.setBorder(BorderFactory.createEmptyBorder(4,4,4,4));
splash.pack(); splash.setLocationRelativeTo(null);
splash.show(); // the line 631 of my code
// SNIP ...Regards,
