             Summary: org.apache.http.client.utils.URLEncodedUtils.parse(URI, 
Charset) should return a new ArrayList when there are no query parameters
                 Key: HTTPCORE-500
                 URL: https://issues.apache.org/jira/browse/HTTPCORE-500
             Project: HttpComponents HttpCore
          Issue Type: Bug
          Components: HttpCore
    Affects Versions: 5.0-beta1, 4.4.8
            Reporter: Gary Gregory
            Assignee: Gary Gregory


{{org.apache.http.client.utils.URLEncodedUtils.parse(URI, Charset)}} should 
return a new {{ArrayList}} when there are no query parameters.

Currently, {{org.apache.http.client.utils.URLEncodedUtils.parse(URI, Charset)}} 
returns an immutable list through {{Collections.emptyList()}} if there are no 
params> But if there are parameters, the method returns a mutable list.

This makes it impossible to write the same code to handle both cases.

This change will cause the method to return a new {{ArrayList}} if there are no 
parameters.
