source code line which caused error:

public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {



I don't remember to encounter such error before.
Ubuntu 20.04

Any idea please ?

Not many Java devs here. Best to ask programming questions on a Java programming forum.
The first line says that /usr/lib/jvm/java-11-openjdk-amd64/lib/libawt_xawt.so can't be opened.
Did you check whether it exists?
If it does not exist on the system, you'll need to find the package which includes that shared library.

Thank you. This has solved the issue:

apt-get install openjdk-11-jre
