We (I) introduced a regression in 1.1.5 while doing another fix. When a relative URL is given for a systemresource URL, the resulting URL is malformed
and an exception is raised.

Here is a regression test:

/* @test -------

@summary regression: relative systemResource URLs are broken in 1.1.5
@author Eduardo Pelegri-Llopart
*/

import java.net.URL;

public class RelativeSysResource {

    public static final String className = "RelativeSysResource.class";
    public static final String javaName = "RelativeSysResource.java";

    public static void main(String[] args) {
try {
URL url = RelativeSysResource.class.getResource(className);
System.out.println("url = " + url);

// create a relative URL using the obtained URL
URL relativeURL = new URL(url, javaName);
System.out.println("relativeURL = " + relativeURL);
} catch (Exception e) {
e.printStackTrace();
}
    }
}
