ERR  java.lang.NullPointerException
        at javax.swing.plaf.synth.SynthStyle.installDefaults(
        at javax.swing.plaf.synth.SynthLookAndFeel.updateStyle(

In order to be able to bring up the UI you will need override the default look and feel.  To do this edit the application’s properties file and add:

FClient.lookAndFeelClassName = javax.swing.plaf.metal.MetalLookAndFeel
