In JDK 1.8, the following methods of java.lang.SecurityManager were deprecated:

boolean SecurityManager.checkTopLevelWindow(java.lang.Object)
void SecurityManager.checkSystemClipboardAccess()
void SecurityManager.checkAwtEventQueueAccess()
void SecurityManager.checkMemberAccess(java.lang.Class,int)

In JDK 9, the methods were marked for removal as part of JDK-8145468.

Also in JDK 9, the first three methods were changed to check AllPermission by JDK-8029886, and in JDK 10 checkMemberAccess was changed to check AllPermission by JDK-8186535.

These methods should be removed from a subsequent JDK feature release, possibly JDK 11.

(Other terminally deprecated SecurityManager APIs that had been deprecated since JDK 1.2 were removed from JDK 10. See JDK-8186535.)
