> In the current code, if the class specified by the JobTracker instrumentation config
property is not there, the JobTracker fails to start with a ClassNotFound.  If it's there,
but it can't load for whatever reason, the JobTracker continues with the default.  Having
two different error-handling routes is a bit confusing; I propose to move one line so that
it's consistent.  (On the TaskTracker instrumentation side, if any of the multiple instrumentations
aren't available, the default is used.)
> The attached patch merely moves a line inside of the try block that's already there.
