Description

Validate a URL using the file scheme/protocol for a file on a local Linux filesystem returns false. An extensive set of tests can be found here: URLTest.java.

The following code snippet is a quick proof-of-concept:

import org.apache.commons.validator.UrlValidator;

class URLTest {

	public static void main(String[] args) {
		String url = "file:///etc/hosts";
		UrlValidator urlValidator = new UrlValidator(new String[] {"http", "https", "ftp", "gopher", "file"});
		boolean result = urlValidator.isValid(url);
		System.out.println(String.format("URL '%s' is valid: %s", url, result));
	}

}

This issue occurs whether the scheme String[] constructor or the ALLOW_ALL_SCHEMES equivalent is used.
