Description
Consider this test class:
---
import java.net.URI;
import java.net.URISyntaxException;
import java.nio.file.Paths;
public class JrtFsTest {
public static void main(String[] args) throws URISyntaxException {
Paths.get(new URI("jrt:/"));
}
}
---
Compile it, and run it on JDK 8 like:
jdk8/bin/java -classpath <JDK9-image>/jrt-fs.jar:<path-to-test> JrtFsTest
This fails with:
---
