Hello again, deprecateds :-) The X errors are from your window manager,
complaining about a toplevel which is too small (for its decorations). Here is a
fix:

$ diff Frame.java ~/kaffe-1.0.b1/libraries/javalib/java/awt/Frame.java 
86,97d85
< public Dimension getPreferredSize () {
<       Dimension d = super.getPreferredSize();
< 
<       d.width  += 2*Defaults.FrameBorderWidth;
<       d.height += Defaults.TitleBarHeight + Defaults.BottomBarHeight;
< 
<       if ( bMenu != null )
<               d.height += Defaults.MenuBarHeight;
< 
<       return d;
< }
< 

Of course, you also have to add the deprecated "preferredSize()" to Component.
I also increased the default width of TextFields:

$ diff TextField.java
~/kaffe-1.0.b1/libraries/javalib/java/awt/widgets/TextField.java  166c166
<       int cx = 80;
---
>       int cx = 50;
170c170
<               cx = Math.max( cx, 15* fm.charWidth( 'm'));
---
> //            cx = Math.max( cx, fm.stringWidth( label));
173d172
< 

Otherwise, the resize(..) / setBounds(..) should be superfluous (which is even
the pack() - with kaffe).
