When I try to launch the JAR or to execute Lexi.java, I get an exception:
Exception in thread "main" java.lang.ClassCastException: javax.swing.plaf.synth.SynthDesktopPaneUI$SynthDesktopManager cannot be cast to com.jmonkey.office.lexi.DocumentManager
    at com.jmonkey.office.lexi.Lexi.getDesktopManager(Lexi.java:711)
    at com.jmonkey.office.lexi.Lexi.createMenuBar(Lexi.java:491)
    at com.jmonkey.office.lexi.Lexi.init(Lexi.java:1038)
    at com.jmonkey.office.lexi.Lexi.<init>(Lexi.java:413)
    at com.jmonkey.office.lexi.Lexi.main(Lexi.java:1069)

I'm using Linux, with Sun Java6 SDK (under Eclipse for the .java execution)
