Thanks, Johan. Can we compare build environments? I cross-compile on Ubuntu 20.04.1 LTS. I followed the instructions at [Cross Building for ARM Hard Float][1] to fetch the toolchain. I use OpenJDK 14.0.2, Ant 1.10.7, and Gradle 6.3, by sourcing this script:

# Sets up the environment for building JavaFX
syspath=/usr/sbin:/usr/bin:/sbin:/bin

export JAVA_HOME=/usr/lib/jvm/java-14-openjdk-amd64
export ANT_HOME=/usr/share/ant
export GRADLE_HOME=$HOME/opt/gradle-6.3

# JDK_HOME and PATH are required by the build
export JDK_HOME=$JAVA_HOME
export PATH=$GRADLE_HOME/bin:$ANT_HOME/bin:$JAVA_HOME/bin:$syspath

I build with the command:

ubuntu at openjfx:~/src/jfx$ gradle -PCOMPILE_TARGETS=armv6hf
