          Patch attached. If this goes in, I'll file another follow-on JIRA to remove the getFileBlockStorageLocations API from trunk since it is superceded by storage IDs.

          Whitespace-only changes patch attached. javac warnings are all because of the additional deprecation. checkstyle is because I followed code style of rest of BlockLocation.

          Thanks for reviewing Eddy, committing this since it's just whitespace changes.
