Unable to launch GUI mode if using DisplayLink driver for external monitors

**Jodster** ([Bug 63369](https://bz.apache.org/bugzilla//show_bug.cgi?id=63369&redirect=false)):
When using a docking station/external monitor that uses the DisplayLink driver, Jmeter gui fails to launch. I have tried several versions of jmeter all with the same result. A similar issue was documented: https://github.com/oracle/visualvm/issues/84

Machine Specs:
MacBook Pro 2015 with Mojave (Ver 10.14.4)
Java 1.8.0_211
JMeter - have tried 5.0 and 5.1.1
DisplayLink driver 5.1.1
Docking stations: Dell doc and Plugable USB 3.0

Steps:
connect to a docking station that uses the DisplayLink driver.
Try to launch jmeter gui

Expected:
jmeter gui launches

Actual:
An error occurred: null

Log file shows:

Workaround: dont use a docking station

Severity: normal
OS: All

Start with org.apache.jmeter.SplashScreen at SplashScreen.java:45 and the JMeter.startGui entry point in JMeter.java:375, using the supplied Java AWT stack trace to investigate startup under a DisplayLink docking setup. Reproduce the failure with the listed Java and macOS versions; done means the JMeter GUI launches instead of raising the reported NullPointerException.
