Problems Launching NetBeans 8.2 on Mac Running High Sierra and DisplayLink USB Video Driver

Javier Lopez
NetBeans 8.2 launches fine when no USB monitor is attached; via DisplayLink; http://www.displaylink.com/downloads/macos.  However, when launching NetBeans 8.2 with secondary monitor connected I get the following error in the NetBeans log:

java.lang.NullPointerException

        at java.awt.Window.init(Window.java:497)

        at java.awt.Window.<init>(Window.java:537)

        at java.awt.Frame.<init>(Frame.java:420)

        at org.netbeans.core.startup.Splash.setRunning(Splash.java:158)

        at org.netbeans.core.startup.Main.start(Main.java:296)

        at org.netbeans.core.startup.TopThreadGroup.run(TopThreadGroup.java:123)

        at java.lang.Thread.run(Thread.java:748)



Complete log attached.



Any advise?
