Due to modularisation, the methods java.lang.SecurityManager.checkAwtEventQueueAccess(), java.lang.SecurityManager.checkSystemClipboardAccess() and java.lang.SecurityManager.checkTopLevelWindow(java.lang.Object) have been removed, so that the core SecurityManager class does not depend on the AWT stack.

When
a Java class uses java.lang.SecurityManager.checkAwtEventQueueAccess(), java.lang.SecurityManager.checkSystemClipboardAccess() or java.lang.SecurityManager.checkTopLevelWindow(java.lang.Object)

Perform
add a hint to replace with a class to checkPermission(java.security.Permission) as follows:

• java.lang.SecurityManager.checkAwtEventQueueAccess() --> java.lang.SecurityManager.checkPermission(new AWTPermission("accessEventQueue"))
• java.lang.SecurityManager.checkSystemClipboardAccess() -->
  java.lang.SecurityManager.checkPermission(new AWTPermission("accessClipboard"))
• java.lang.SecurityManager.checkTopLevelWindow(java.lang.Object) --> java.lang.SecurityManager.checkPermission(new AWTPermission("showWindowWithoutWarningBanner"))
