I have another question. I don't know much about Akka (hardly anything,
really), and I was wondering, if you forward the message, would this try/catch
(in the `JobManager` actor) be able to capture exceptions that were thrown in
the archive actor? If not, then a try/catch should also be used in
`MemoryArchivist`.

> Key: FLINK-2388
> URL: https://issues.apache.org/jira/browse/FLINK-2388
> Project: Flink
> Issue Type: Task
> Components: JobManager
> Reporter: Enrique Bautista Barahona
>
> I was following the quickstart guide with the WordCount example and, when I
> entered the "analyze" page for the job, nothing came up. Apparently the
> JobManagerInfoServlet fails with a NullPointerException.
> I've been reading the code and I've seen the problem is in the processing of
> the RequestAccumulatorResultsStringified message in JobManager. There's a
> TODO where the accumulators should be retrieved from the archive.
> As I wanted to know more about Flink internals, I decided to try and fix it.
> I've later seen that there's currently ongoing work in that part of the code,
> so I guess maybe it's not needed, but if you want I could submit a PR. If you
> have already taken it into account and will solve it shortly, please feel
> free to close the issue.
> If you want to take a look, the commit is here:
