Problem Description

If you build examples/webserver/streaming and run it with java -jar it fails with:

# This is from Helidon 4.0.6 example
$ java -jar target/helidon-examples-webserver-streaming.jar
Exception in thread "main" java.nio.file.FileSystemNotFoundException
	at jdk.zipfs/jdk.nio.zipfs.ZipFileSystemProvider.getFileSystem(ZipFileSystemProvider.java:156)

	at java.base/java.nio.file.Path.of(Path.java:209)

	at io.helidon.examples.webserver.streaming.Main.main(Main.java:47)

Also, the README for the 4.x example looks wrong as it mentions Subscriber<DataChunk> and Producer<DataChunk>

And I wonder if it makes more sense for the file to come from the filesystem and not a (jar) resource.
