Could not initialize class javax.swing.plaf.basic.BasicOptionPaneUI

Hello,

I am updating an application, where I use 'JOptionPane'.

While the old version (about one year old) worked fine I now get the above shown message due to
an

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError:

What do I have to change/add in order to prevent that exception?

Thanks for your help.
