Would be good to log `t` in trace over here.
> Transaction client should not retry startShort() if an invalid timeout is
> given

> Key: TEPHRA-194
> URL: https://issues.apache.org/jira/browse/TEPHRA-194
> Project: Tephra
> Issue Type: Bug
> Components: client
> Affects Versions: 0.9.0-incubating, 0.10.0-incubating
> Reporter: Andreas Neumann
> Assignee: Andreas Neumann
> Fix For: 0.10.0-incubating
>
>
> Currently, if an invalid timeout (negative, or too long) is given, the Tx
> manager throws an IllegalArgumentException. The thrift client will catch that
> and apply the retry strategy. However, in this case, retry is pointless, and
> if the strategy is, for example, exponential backoff, if introduces
> unneccessary load and latency.
> The service should instead throw a meaningful exception for that, so that the
> client knows not to retry.
