In the source code (java.awt.font.TextAttribute), they are defined as:

    /**
     * Left-to-right run direction.
     * @see #RUN_DIRECTION
     */
    public static final Boolean RUN_DIRECTION_LTR = new Boolean(false);

    /**
     * Right-to-left run direction.
     * @see #RUN_DIRECTION
     */
    public static final Boolean RUN_DIRECTION_RTL = new Boolean(true);

But in the javadoc spec (TextAttribute.RUN_DIRECTION), it says:

    Constants
    RUN_DIRECTION_LTR = true, RUN_DIRECTION_RTL = false

To keep the compatibility, we need to align the spec to the implementation.
