NumberFormatException from FileUtils.toFile method
--------------------------------------------------

                 Key: IO-252
                 URL: https://issues.apache.org/jira/browse/IO-252
             Project: Commons IO
          Issue Type: Bug
          Components: Utilities
    Affects Versions: 1.4
            Reporter: Valrith


Certain strings can cause the org.apache.commons.io.FileUtils.toFile(URL url) 
method to call Integer.parseInt with an invalid argument and thus throw a 
NumberFormatException:

Exception in thread "main" java.lang.NumberFormatException: For input string: 
"%2"
        at 
java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
        at java.lang.Integer.parseInt(Integer.java:449)
        at org.apache.commons.io.FileUtils.toFile(FileUtils.java:476)

One example of such a string: "both%20are%20100%20%25%20true"
