Changes requested by amitkumar (Author).

src/java.base/share/classes/jdk/internal/loader/URLClassPath.java line 211:

> 209:         this.unopenedUrls = unopenedUrls;
> 210:         this.path = path;
> 211:         // the application class loader uses the built-in protocol handler to avoid protocol

It should have been a clean backport. Please remove these two imports from this file: 


import java.util.HashSet;
import java.util.Set;


Also please mention about testing you have done for this patch !!
