In TextArea.java, a line seems to be missing from the javadoc comment
for constructors that take a string as an argument.

Here is an example:

    /**
     * Constructs a new text area with the specified text.
     * This text area is created with scrollbar visibility equal to
     * {@link #SCROLLBARS_BOTH}, so both vertical and horizontal
     * scrollbars will be visible for this text area.
     * @param text the text to be displayed; if
     * <code>text</code> is <code>null</code>, the empty
     * @exception HeadlessException if GraphicsEnvironment.isHeadless()
     * returns true.
     * @see java.awt.GraphicsEnvironment#isHeadless
     */
    public TextArea(String text) throws HeadlessException {
        this(text, 0, 0, SCROLLBARS_BOTH);
    }

The error is in the param tag:
     * @param text the text to be displayed; if
     * <code>text</code> is <code>null</code>, the empty

There should be an additional line:
     * string <code>""</code> will be displayed

This line is missing from several constructors.
