Description

1) New tait to include logging and helper methods so if (log.isDebugEnabled()) is not required because it is in the helper and log paramaters are passed by name so not executed to tidy up the code

2) refactor all occurrence of logging to use the log helper

3/4 (possibly to be handled in to tickets) the "lint" affect from this for changes patched but not on trunk and new patches moving forward until this is baked in
