    Because (like in this case), an AWT component might actually be

    implemented using Swing,<br>

    the recommendation is to treat AWT components like Swing, and update

    them only on the EDT.<br>

        <div>I've discovered that on X11 platforms a call

          of java.awt.TextComponent#setText can lead to a call

          of javax.swing.JComponent#paintImmediately(java.awt.Rectangle)

          on the same thread.</div>

        <div>Since java.awt.TextComponent#setText is allowed to be

          called on any thread (because it's AWT, not Swing),

          JComponent#paintImmediately may be called outside of EDT. Is

          this a valid behavior?</div>
