Description

After registering the FsUrlStreamHandlerFactory with the JVM, subsequent calls to convert a "file" URL to a URI can fail with "Illegal character in path" where the illegal character is a backslash.

For example:

URL.setURLStreamHandlerFactory(new FsUrlStreamHandlerFactory());
File file = new File("C:/Users");
final URL url = new URL("file:///" + file.getAbsolutePath());

gives stack trace:

java.net.URISyntaxException: Illegal character in path at index 8: file:/C:\Users
