Class java.awt.font.TextLayout overrides method equals() which says:

    /**
     * Returns <code>true</code> if the specified <code>Object</code> is a
     * <code>TextLayout</code> object and if the specified <code>Object</code>
     * equals this <code>TextLayout</code>.

In fact it happens only if layouts are the same instance.
