 The sun.awt.motif.X11Selection and sun.awt.motif.MDrawingSurfaceInfo
throw UnsatisfiedLinkError in JDK-1.2fcs-A.

The example:
------------------------------8-<--------------------------------------------
public class test {
public static void main(String s[]) {
  try {
   System.out.println(Class.forName("sun.awt.motif.X11Selection"));
   System.out.println("sun.awt.motif.X11Selection - OKAY");
  } catch (Throwable e) { e.printStackTrace();}
    
  try {
   System.out.println(Class.forName("sun.awt.motif.MDrawingSurfaceInfo"));
   System.out.println("sun.awt.motif.MDrawingSurfaceInfo - OKAY");
  } catch (Throwable e) { e.printStackTrace();}

 }
}

###@###.### 1998-10-12 :

    Yes, this bug not reproducible if initialize the AWT via the
creation new Frame and making it visible as recommended above but
the test gets SEGV if only create a Frame object.

1. No 'new Frame()' invokation UnsatisfiedLinkError
2. Only 'new Frame()' invokation SEGV
3. new Frame() + setVisible(true) OKAY

----------------------------------------------------------------------------
public class Test {
public static void main(String s[]) {
  java.awt.Frame f = new java.awt.Frame(); // Add f.setVisible(true) to pass
  try {
   System.out.println(Class.forName("sun.awt.motif.X11Selection"));
   System.out.println("sun.awt.motif.X11Selection - OKAY");
  } catch (Throwable e) { e.printStackTrace();}
    
  try {
   System.out.println(Class.forName("sun.awt.motif.MDrawingSurfaceInfo"));
   System.out.println("sun.awt.motif.MDrawingSurfaceInfo - OKAY");
  } catch (Throwable e) { e.printStackTrace();}
