Why does JRuby Swing app quits immediately if run as jar

I am trying to build a simple JRuby application with a GUI. I am using the code in this page as a starting point, section marked "Simple Example".
If I take the code snippet and I run it as
$> jruby test.rb
then it is all fine, I see the window.
If I try to make a "jar" file and run it with:
$> warble jar
$> java -jar test.jar
Then the application immediately exists without leaving an error code.
I tried to run the "jar" file in Windows10 and FreeBSD11.2, same behaviour, the GUI immediately quits.
Do you know how can I work around this ?
Sorry for the simple question, these are my first steps with JRuby.

Main thread ends afterExample.new. Invoke it with a new thread and SwingUtilities. The repl acts as a main thread when you run it as a snippet.

After Elliott suggestion I made the following modification to the last line of the original code and the "jar" works. It is just a hack, but small enough to get a beginner, like me, on track;)
t1 = Thread.new {
Example.new
}
while true do
sleep 1
end
