Geoffrey De Smet resolved JBRULES-3387.
---------------------------------------

    Resolution: Done


Fixed like this:
{code}
java.lang.IllegalStateException: Phase localSearch started with an uninitialized Solution. First initialize the Solution. For example, run a phase constructionHeuristic first.
