> My IDE flags a lot of trouble in the JobTracker code, but I dont want to mix those changes with any lifecycle changes. After doing that, then I'd like to clean up the code in JobTracker
> -move to generic types and foreach loops over Vector and iterators.
> -give all threads the correct type
> -stop using package scoped static variables to pass instance-data around specifically 
>  TASKTRACKER_EXPIRY_INTERVAL
>  RETIRE_JOB_CHECK_INTERVAL
>  RETIRE_JOB_INTERVAL
> -fix up all the javadoc warnings 
> -remove the needless this. references on lots of local variables
> -replace the log + stringifyException with log(text,exception). 
> Its only an hour or so of work, and would improve the code maintainability, but it would  make merging existing code harder.
