RegTest-CTE CTE_REGTEST/Generic/4394882/Rotate.java test incorrectly renders the content
of the frame after some window that overlaps the frame is moved. The test treats the
upper-left corner of the clipping area to be repainted as actual upper-left corner of the frame.
Because of this and because the the test frame always appears behind the test description window
it is very hard to evaluate the test result. The same behavior is observed as using JDK1.4.2-b14
as using JDK1.4.1-b21.

After I had modified Rotate.java as follows:

    public static class MyCanvas extends javax.swing.JComponent
    {
        public void paintComponent(java.awt.Graphics p1)
        {
// OPTIONAL MODIFICATION - as suggested by the paintComponent specification,
// but the test renders properly without this modification -->
            java.awt.Graphics2D g2 = (java.awt.Graphics2D)p1.create();
// <-- OPTIONAL MODIFICATION
            //
            g2.setRenderingHint(java.awt.RenderingHints.KEY_ANTIALIASING,
                       java.awt.RenderingHints.VALUE_ANTIALIAS_ON ); //_OFF
            g2.setFont( new java.awt.Font( "Helvetica", java.awt.Font.BOLD, 12 ) );
            //
// KEY MODIFICATION - the test pains in the clipping area, not in the frame -->
            java.awt.Rectangle rect=g2.getClipBounds();
// <-- KEY MODIFICATION
            for( double angle = 0; angle< 360; angle+=15 )
            {
                String text = "Test_rotate_0123456789_Test_rotate_end";
                java.awt.geom.AffineTransform af = new java.awt.geom.AffineTransform();

// KEY MODIFICATION - the test pains in the clipping area, not in the frame -->
                af.translate( 400-rect.x, 400-rect.y );
// <-- KEY MODIFICATION
                af.rotate( Math.toRadians( angle ) );
                g2.setTransform( af );
                //
                g2.setColor( java.awt.Color.black );
                g2.drawString( text, 0, 0 );
                g2.setColor( java.awt.Color.red );
                g2.drawLine(0, 0, 400, 0 );
            }
          //
        }

    }

the test rendered its content properly and
its "PASSED" conditions were satisfied (the circle at the center was round).
