You are right indeed. Changing that sample code to something like:
final JarFile jarFile = new JarFile(tmpDir + File.separator + "abc\0xyz");
does indeed end up throwing a java.nio.file.InvalidPathException even on
*nix, on Java 11.
I don't have access to create an issue for this in OpenJDK JIRA, so I'll
go ahead and create one at bugs.java.com.
