   * The table size is capped because, when there are more threads
   * than CPUs, supposing that each thread were bound to a CPU,
   * there would exist a perfect hash function mapping threads to
   * slots that eliminates collisions. When we reach capacity, we
   * search for this mapping by randomly varying the hash codes of

     * If the given language is {@code null}, then this method returns the enabled sources for all languages.
     * An arbitrary number of source roots may exist for the same scope and language.
     * It may be, for example, the case of a multi-versions project.
     * The iteration order is the order in which the sources are declared in the POM file.
