> ResourceBundle lookup during counter name resolution takes a lot of time

> Loading a job status page in trunk takes a lot of time, and it seems like
> most of the time is spent resolving counter names. Looking through the JDK
> source, ResourceBundle.getBundle(String) ends up calling getClassContext()
> which is not very efficient. I think if we pass our own classloader manually
> it will be faster. In Counters.incrAllCounters, we may also be able to avoid
> setting the counter name if one is already set.
