            Bug ID: 55434
           Summary: The path /foo/a/a/bar causes IllegalArgumentException
                    when WsServerContainer creates UriTemplate
           Product: Tomcat 8
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
          Assignee: dev@tomcat.apache.org
          Reporter: rstoyanc...@yahoo.com

WsFilter calls WsServerContainer.findMapping("/foo/a/a/bar"), which in turn
calls new UriTemplate(path). If the path contains repeated segments, it causes
the following code in the UriTemplate constructor to throw an exception:

Segment old =
        this.segments.put(segment, new Segment(index, segment));
if (old != null) {
    throw new IllegalArgumentException(
            sm.getString("uriTemplate.duplicateName", segment));
}

This would be valid if the duplicates were URI variable names but not when
their plain path segments.
