Review Comment:
the test is not brittle - if someone changes the format of the exception
message, it could break but that would be sort of expected if you go changing
the format of exception messages
> check that class that is loaded is really an exception

> Key: HADOOP-19079
> URL: https://issues.apache.org/jira/browse/HADOOP-19079
> Project: Hadoop Common
> Issue Type: Task
> Components: common, security
> Reporter: PJ Fanning
> Priority: Major
> Labels: pull-request-available
>
> It can be dangerous taking class names as inputs from HTTP messages even if
> we control the source. Issue is in HttpExceptionUtils in hadoop-common
> (validateResponse method).
> I can provide a PR that will highlight the issue.
