Could not initialize class javax.swing.plaf.basic.BasicOptionPaneUI
879227Jul 31 2011 — edited Aug 1 2011Hello,
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.
