@foer This is a localization bug in greenfoot. The warning is suppressed when english language is used. Other language settings (in your case german) still show this warning.

Within BlueJ this has been fixed. I expect this to be fixed upstream with the next greenfoot release.

Starting with Greenfoot 3.8.0-1 there is a warning on startup:

WARNUNG: Unsupported JavaFX configuration: classes were loaded from 'unnamed module @3a62b39e

It seems that it's only a warning and have no effect on functionality but students are very irritated by that. Is there a possibility to solve that problem?

Update: Linkin to Openjdk11 and java11-openjdk in /usr/bin/greenfoot stops the warning. It must have something to do with java17...

Thank you so much for taking over the project! I've been following your advice to build the package and it has worked perfectly so far. Cheers

I did following changes locally to also have mime-types set correctly, to be able to open greenfoot when project.greenfoot is clicked.

Changed greefoot:

if [ -e /usr/lib/jvm/java-11-openjfx/lib ]; then


archlinux-java-run -a 11 -b 11 -- -Djavafx.embed.singleThread=true \
        -Dawt.useSystemAAFontSettings=on \
        -cp /opt/greenfoot/bluej.jar:/usr/lib/jvm/default/lib/tools.jar:$JAVAFX_CP bluej.Boot \
        -greenfoot=true \
        -bluej.compiler.showunchecked=false \
        -greenfoot.url.javadoc=file:///usr/share/doc/greenfoot/API \
        -javafxpath=$JAVAFX_CP \

Changed greenfoot.desktop

[Desktop Entry]
Comment=A simple Java IDE and animation framework
Exec=greenfoot %u

Added greenfoot.xml

<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="">
  <mime-type type="application/x-greenfoot.package">
         <comment>Greenfoot Package</comment>
         <comment xml:lang="de">Greenfoot Paket</comment>
         <glob pattern="*.greenfoot"/>

Added greenfoot.install

post_install() {
    if test -x /usr/bin/update-mime-database usr/share/mime &> /dev/null; then update-mime-database usr/share/mime &> /dev/null; fi

post_upgrade() {

pre_remove() {
    if test -x /usr/bin/update-mime-database usr/share/mime &> /dev/null; then update-mime-database usr/share/mime &> /dev/null; fi

Changed source and sha256sum lines in PKGBUILD and added

install -Dm644 "${pkgname}.xml" "${pkgdir}/usr/share/mime/packages/${pkgname}.xml"

@chetgurevitch Have you found time to verify that the modifications are working? Here is the code of the greenfoot file:


if [ -e /usr/lib/jvm/java-11-openjfx/lib ]; then JAVAFX_HOME=/usr/lib/jvm/java-11-openjfx else JAVAFX_HOME=/usr/lib/jvm/java-11-openjdk fi


archlinux-java-run -a 11 -b 11 -- -Dawt.useSystemAAFontSettings=on \ -cp /opt/greenfoot/bluej.jar:/usr/lib/jvm/default/lib/tools.jar:$JAVAFX_CP bluej.Boot \ -greenfoot=true \ -bluej.compiler.showunchecked=false \ -greenfoot.url.javadoc=file:///usr/share/doc/greenfoot/API \ -javafxpath="$JAVAFX_HOME" \ "$@"

The new version 3.6.1 (6 Dec 2019) works with the modifications by @foer. Tested it on 8 Dec 2019. No issues like the ones mentioned in my comment on 8 Nov.

Thanks a lot to all the people who contribute to this aur, especially to @chetgurevitch
