The file system provider will add the prefix is required when doing file I/O but it doesn't expose in the String representation, meaning Path::toString will not return a String with this prefix. When you have relative paths that are really long then you'll see the rational for this long standing policy. Since JDK 21, Path.of(String) will accept a file path that has the prefix, it will be dropped of course when parsing and normalizing the input. Being liberal on what you accept here is allow for file paths that come from native programs. ------------- PR Comment: https://git.openjdk.org/jdk/pull/31209#issuecomment-4517658108
