> Please review these small changes to address intermittent failures, as of 
> JDK-8274517.
> - Usage of jdk.test.lib.RandomFactory for reproducible random generation.
> - Slightly less restrictive assertion about badParallelStreamError on L94

> - Verbatim copy of computeFinalSum() from j.u.s.Collectors 18.
> While these changes do not necessarily guarantee absence of intermittent

> There is still an inherent variability due to the use of parallel streams, 
> though. As double addition is not perfectly associative, even a fully known 
> sequence of doubles may lead to slightly different results with 
> parallelization.

Anybody interested in reviewing?
