My B4J application with MediaManager showing a picture (from a file) is running well under Windows.
The same running on RaspBerry Linux shows following error :

I guess issue is coming from JavaFx
For information, level of installed Java on Rapsberry is as follows :
pi@raspberryCR:~ $ java -version
openjdk version "11.0.11" 2021-04-20
OpenJDK Runtime Environment (build 11.0.11+9-post-Raspbian-1deb10u1)
OpenJDK Server VM (build 11.0.11+9-post-Raspbian-1deb10u1, mixed mode)
Please could you help
