java.awt.swing.ViewportLayout.preferredLayoutSize(parent) throws
undocumented NullPointerException in case parent.getView() returns null.

Here is the test demonstrating the bug:
-----------------Test.java------------------------
import java.awt.swing.*;

class Test {
  public static void main(String[] argv) {
    ViewportLayout layout = new ViewportLayout();
    JViewport parent = new JViewport();
    parent.setView( null);
    try {
      layout.preferredLayoutSize(parent);
      System.out.println(" OKAY ");
    } catch(NullPointerException e) {
      System.out.println(" FAILED : "+e+" has been thrown");
    }
    System.exit(0);
  }
}

---------Output from the test---------------------

  FAILED : java.lang.NullPointerException has been thrown
