Hi Alan, with the fix you have given I got the output for the following 
directory structure.Now all the cycles are getting notified

/java
       Start
              DirP
                    DirQ
                            DirT
                                    dirVlink - > Start/DirP/DirV
                     DirV
                             start_link -> /java/Start
                      dirTlink_forward -> Start/DirP/DirQ/DirT
               DirJ
                      dirjfile


output: Files.walkFileTree(Paths.get("/java"), 
EnuSet.allOf(FileVisitOption.class),-1,new MyFileVisitor());
