Confirmed.  As a test case, you merely need to add a component to a component
using the ScrollPaneLayout:

  public TestSwing()
  {
    setLayout(new ScrollPaneLayout());                                          
    add(new JButton());                                                         
  }

This runs on IcedTea but fails on Classpath:

Exception in thread "main" java.lang.IllegalArgumentException
   at
javax.swing.ScrollPaneLayout.addLayoutComponent(ScrollPaneLayout.java:148)
   at java.awt.Container.addImpl(Container.java:392)
   at java.awt.Container.add(Container.java:297)
   at javax.swing.JFrame.addImpl(JFrame.java:264)
   at java.awt.Container.add(Container.java:230)
   at TestSwing.<init>(TestSwing.java:12)
   at TestSwing.main(TestSwing.java:17)

The error is not in ScrollPaneLayout.  Changing the code to:

    ScrollPaneLayout l = new ScrollPaneLayout();
    l.addLayoutComponent("", new JButton());

correctly triggers an IllegalArgumentException on both IcedTea and Classpath:

$ cacao TestSwing
Exception in thread "main" java.lang.IllegalArgumentException
   at
javax.swing.ScrollPaneLayout.addLayoutComponent(ScrollPaneLayout.java:148)
   at TestSwing.<init>(TestSwing.java:12)
   at TestSwing.main(TestSwing.java:19)

$ /usr/lib/icedtea6/bin/java TestSwing
Exception in thread "main" java.lang.IllegalArgumentException: invalid layout
key 
        at
javax.swing.ScrollPaneLayout.addLayoutComponent(ScrollPaneLayout.java:257)
        at TestSwing.<init>(TestSwing.java:12)
        at TestSwing.main(TestSwing.java:19)
