One more note to this commit.
java.net.URI.toURL() is implemented as the following in JDK 8u72
public URL toURL()
throws MalformedURLException {
if (!isAbsolute())
throw new IllegalArgumentException("URI is not absolute");
return new URL(toString());
}
The above does File -> URI -> String -> URL, URL -> String -> String -> URL.
1. I do not see any testcases in this commit.
The last step performs parsing of String into URL. It needs a testcase
that the parsing performed by (new URL(fileUrlString)) does not
convert "%21/" back to "!/", nullifying the efforts.
2. It will be cheaper to process the String generated from
URI.toString(), making it
File -> URI -> String -> String -> URL.
String fileUriString = file.toURI().toString();
fileUriString = fileUrlString.replaceAll("!/", "%21/");
return new URL(fileUrlString);
