Bug? Error "VetoableListDecorator"

Hello, I have a problem, I am running a jar prog in ubuntu and declaring all the modules [java.base, java.desktop, java.instrument, java.logging, java.management, java.management.rmi, java.naming, java.rmi, java.security.jgss, java.security.sasl, java.sql, java.transaction.xa, java.xml, javafx.base, javafx.controls, javafx.fxml, javafx.graphics, javafx.media, javafx.swing, java.scripting, jdk.unsupported, java.datatransfer, jdk.unsupported.desktop, jdk.jsobject, jdk.xml.dom]

An error comes up when I open a form using B4XPreferencesDialog, if I set a fieldin the json file with options to "Short Options" , then no errors , if I simply change to "Options" (the only change I make) I get this: "Caused by: java.lang.IllegalAccessException: class anywheresoftware.b4j.object.JavaObject cannot access class com.sun.javafx.collections.VetoableListDecorator (in module javafx.base) because module javafx.base does not export com.sun.javafx.collections to unnamed module @2d236ab3" and nothing shows up in the options list.

Java runtime in ubuntu is:

openjdk version "11.0.8" 2020-07-14
OpenJDK Runtime Environment (build 11.0.8+10-post-Ubuntu-0ubuntu118.04.1)
OpenJDK 64-Bit Server VM (build 11.0.8+10-post-Ubuntu-0ubuntu118.04.1, mixed mode, sharing)

As a note the same jar prog. in Windows runs ok in both cases.

Seems like I am maybe missing a library in ubuntu, can someone give me some advice ? Thanks

Doesn't look like the correct Java version.

Download java from: https://www.b4x.com/android/forum/t...lest-way-to-distribute-ui-apps.99835/#content

(I'm not sure whether it will solve this issue or not, but start with this)

Thanks for the reply, ok installed specific version:

openjdk version "11.0.1" 2018-10-16
OpenJDK Runtime Environment 18.9 (build 11.0.1+13)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode)

Same error unfortunately:

Any other ideas , seems a strange error...

I've tested it with OpenJDK 14: https://www.b4x.com/android/forum/t...lest-way-to-distribute-ui-apps.99835/#content

Works fine:

Thanks for the reply , but I am still getting the error even with 14 in ubuntu 18 :
openjdk version "14.0.1" 2020-04-14
OpenJDK Runtime Environment (build 14.0.1+7)
OpenJDK 64-Bit Server VM (build 14.0.1+7, mixed mode, sharing)

I am now using the example directly : https://www.b4x.com/android/forum/attachments/preferencesexample-b4j-zip.81852/ to further exclude any errors in my prog.

I am compiling with v. 11 , do I need to compile with v.14 ? if yes I presume I will need compiled javafx ver 14 for windows ? ( I can find only linux)

I don't think that it will make any difference but please try it: https://www.b4x.com/android/forum/threads/b4j-v8-30-beta-is-available-for-download.117877/#content
