Gilles commented on LANG-1196:
------------------------------
bq. easy fix would be to pass the Random implementation in the constructor
{{RandomSringUtils}} is a "_utility_" class: all methods are static. Passing an
argument to the constructor will require to remove the _static_ keyword, which
is not a compatible change.
Better would be to define a specific interface (as suggested by Jochen on the
ML).
Even better would be to have a dedicated Commons component (for random-related
utilities).
There is a willingness to create one based on the RNG interface defined in
http://commons.apache.org/proper/commons-rng/apidocs/org/apache/commons/rng/UniformRandomProvider.html
Please have a look at the "dev" ML archive for recent discussions about the new
"RNG" component.

> Hi,
> I'm using [Sham
> |http://search.maven.org/#artifactdetails%7Corg.shamdata%7Csham%7C0.3%7Cjar]
> to generate realistic looking test data for both parameterized tests and user
> acceptance testing. We log the seed that is used for each run so that if
> there is an issue we can recreate exactly the same test data. I would also
> like to use some of the commons-lang RandomStringUtils functionality but
> notice that the implementation provides no way of setting the random number
> generator to be used.
> {code}private static final Random RANDOM = new Random();{code}
> A way to configure this would be really useful. If there is an alternative
> way to do this then that would be great. If you think it's a good idea and it
> requires a patch I'm happy to supply one.
> Cheers,
> Gus.
