> Reporter: David Mollitor
> Assignee: David Mollitor

> Remove global {{Random}} object in favor of {{ThreadLocalRandom}}.
> {quote}
> ThreadLocalRandom is initialized with an internally generated seed that may
> not otherwise be modified. When applicable, use of ThreadLocalRandom rather
> than shared Random objects in concurrent programs will typically encounter
> much less overhead and contention.
