Bug reported by Corel (licensee) for JFC1.1 using JDK1.1.4 on WINNT4.0.
Corel: "Very critical bug for our product - requires immediate attention."

a. Setup to use the underline style for text formatting
b. Enter text
c. Press <enter> twice to create a couple of blank lines
d. Enter text again
f. Note that there are underscores characters left in the blank lines.

Further to my request to Corel for more info (a test case), Corel responded
with the following fix to the problem (changed code is underlined):

In the file LabelView.java:

final void paintText(Graphics g, Shape a, int p0, int p1) {
    Rectangle alloc = a.getBounds();
    sync();
    loadText(p0, p1);
    int y = alloc.y + alloc.height - metrics.getDescent();
    g.setFont(font);
    g.setColor(fg);
    Utilities.drawTabbedText(text, alloc.x, y, g, expander, p0);
    if (underline && text != null && !text.toString().equals("\n")) {
        y += 1; //------------------------------------------------
        g.drawLine(alloc.x, y, alloc.x + alloc.width, y);
    }
}
