Hello Gabriele.
Thanks for the report.
However, as you might have seen from recent activity on JIRA, or the "Commons"
project "dev" ML, the monolithic "Commons Math" library is being phased out in
favour of smaller, more focused, modular components:
* [Commons RNG|http://commons.apache.org/rng]
* [Commons Numbers|http://commons.apache.org/numbers]
* [Commons Statistics|http://commons.apache.org/proper/commons-statistics/]
* ...
Moreover, although being the last official release, v3.6.1 is obsolete because
of the evolutions (bug fixes and refactoring) that happened on the "master"
branch (geared towards v4.0) during the last 3 years.
This is to say that if you are a heavy user of the {{genetics}} package, and
are able, and willing, to maintain it, you are welcome to signal it on the
"dev" ML. The ensuing discussion would clarify whether a new "Commons Genetics"
component would be acceptable to the project leaders.

> I've found an infinite loop when recombining two integers Chromosomes
> admitting duplicates with CycleCrossover class.
> For example, recombining example Chromosomes it works fine, but, if you
> substitute all "8" with "7", you run into an infinite loop while mating.
> I attach the self-contained unit test (JUnit) for a better comprehension
> (issue a mvn clean install to run).
> I added a little quick patch to fix, which I'm happy to provide, even could
> be less efficient than original.
