org.tuckey.web.filters.urlrewrite.utils.URLEncoder ampersand encoded incorrectly

[GoogleCodeExporter]

What steps will reproduce the problem?
1. System.out.println("encodedPath"+ URLEncoder.encodePathSegment("Events & 
Programs", "UTF-8"));
2.
3.

What is the expected output? What do you see instead?
Expected "Events%20%26%20Programs" (no quotes)
Instead see "Events%20&%20Programs"

What version of the product are you using? On what operating system?
r307 checkin

Please provide any additional information below.
Thank you for your otherwise excellent code. You may want to alter 
URLDecodingTest to use org.tuckey.web.filters.urlrewrite.utils.URLEncoder 
instead of java.net.URLEncoder, and here is another test case:

Add to URLDecodingTest.java:
    @Test
    public void testPathAmpersandEncoding() throws UnsupportedEncodingException {
        String path = "Events & Programs";
        String encodedPath = org.tuckey.web.filters.urlrewrite.utils.URLEncoder.encodePathSegment(path, "UTF-8");
        assertEquals(encodedPath, "Events%20&%20Programs");
    }

The function you are referring to is creating a path segment. & should 
definitely not be encoded as & 

java.net.URLEncoder can be used for encoding the query string

org.tuckey.web.filters.urlrewrite.utils.URLEncoder handles individual path 
parts and path segments.
