The 45 * problem is that this means that the native libraries must be 46 * loaded by the java.* classes, which do not necessarily know the 47 * names of the libraries to load. A better way of doing this 48 * would be to provide a separate library which defines java.awt.* 49 * initIDs, and exports the relevant symbols out to the 50 * implementation libraries. 51 * 52 * For now, we know it's done by the implementation, and we assume 53 * that the name of the library is "awt". -br. 54 */ 55 static void loadLibraries() { 56 java.security.AccessController.doPrivileged( 57 new sun.security.action.LoadLibraryAction("awt")); 58 } 59 }
