Alex Herbert commented on RNG-186:
----------------------------------
In place of `Random`, at least consider `ThreadLocalRandom.current()` or a
`SplittableRandom` instance with the default increment. Both of those RNGs will
pass state-of-the-art tests for randomness (TestU01 BigCrush or PractRand for
several TiB of output). Their limitation is a period of 2^64, which is
sufficient for generating test data. They will also be faster for either true
concurrent usage (`ThreadLocalRandom`), or single thread usage
(`SplittableRandom`). Note that Random has a period of 2^48 and is effectively
synchronized using an AtomicLong for its state.
I can look at the bundle plugin. It is important for our multi-module builds to
ensure we do not get a repeat of this module issue again.

> Key: RNG-186
> URL: https://issues.apache.org/jira/browse/RNG-186
> Project: Commons RNG
> Issue Type: Task
> Components: core, simple
> Affects Versions: 1.5
> Reporter: Richard Eckart de Castilho
> Priority: Major
>
> Commons RNG Simple imports the following packages:
> {noformat}
> Bundle-SymbolicName: org.apache.commons.rng.simple
> Implementation-Version: 1.5
> Import-Package:
> org.apache.commons.rng,org.apache.commons.rng.core,
> org.apache.commons.rng.core.source32,
> org.apache.commons.rng.core.source64,
> org.apache.commons.rng.core.util
> {noformat}
> However, Commons RNG Core does not export the source packages:
> {noformat}
> Bundle-SymbolicName: org.apache.commons.rng.core
> Implementation-Version: 1.5
> Export-Package:
>
> org.apache.commons.rng.core;x-friends:="org.apache.commons.rng.simple";version="1.5.0"
> Private-Package:
> org.apache.commons.rng.core.source32,
> org.apache.commons.rng.core.source64,
> org.apache.commons.rng.core.util
> {noformat}
> Consequently, using Commons RNG simple fails in an OSGi environment as the
> bundle cannot be resolved.
> {noformat}
> [ERROR] Resolution failed. Capabilities satisfying the following requirements
> could not be found:
> [<<INITIAL>>]
> ...
> ⇒ osgi.wiring.package:
> (&(osgi.wiring.package=org.apache.commons.rng.simple)(version>=1.5.0)(!(version>=2.0.0)))
> ⇒ [org.apache.commons.rng.simple version=1.5.0]
