      Description

      Have extends some UI Components to add additonal features. With the Nimbus L&F
      the BaseUI is not working in all cases. See the exception below.
      we does not have control over the L&F and this will be a fatal for our customers.
      This must be fix in the BaseUI classes or in the Nimbus L&F defintion.
      Because the problem occur inside of the Sun classes it is inpossible to compensate it.
