problem running on Ubuntu

[vmdave9]

system: 4.15.0-45-generic #48-Ubuntu SMP Tue Jan 29 16:28:13 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux java version: ./java --version openjdk 11.0.2 2019-01-15 OpenJDK Runtime Environment 18.9 (build 11.0.2+9) OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode) startup script: #!/bin/bash /home/dave/Downloads/jdk-11.0.2/bin/java

--add-modules=javafx.controls
-Dfile.encoding=UTF-8
-jar /home/dave/Downloads/dm3270.jar

However, when I run the script, and click on the connect button I get this error: ./davedm3270.sh setting: IBM-3278-2-E model: 4 setting: IBM-3278-4-E Exception in thread "JavaFX Application Thread" java.lang.IllegalAccessError: class com.bytezone.dm3270.display.FontDetails (in unnamed module @0xc3c194d) cannot access class com.sun.javafx.tk.Toolkit (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.tk to unnamed module @0xc3c194d at com.bytezone.dm3270.display.FontDetails.(FontDetails.java:26) at com.bytezone.dm3270.display.FontManagerType1.setFont(FontManagerType1.java:200) at com.bytezone.dm3270.display.FontManagerType1.(FontManagerType1.java:43) at com.bytezone.dm3270.display.FontManager.getInstance(FontManager.java:12)

I suspect a path is not set up the way it shoud be here. Thanks. DJ
