I think L218 has exceeded 80. 

{code}
+    long elapsedTime = System.currentTimeMillis()
+        - dirFileStatus.getModificationTime();
{code}

A better style is 

{code}
+    long currentTime = System.currentTimeMillis();
+    long elapsedTime = currentTime - dirFileStatus.getModificationTime();
{code}
