For the record:
In your solverConfig, you're missing a |<constructionHeuristic>| section
(use FIRST_FIT) before the |<localSearch>| section, see manual for more
information or most of the examples.
I 'll file a JIRA to get a better exception message when this occurs.

Is it possible setting planning entity with uninitialized planning value into
solution?
if it is possible, then how? :)

When I execute my code with not null planning variables everything work
fine, but when i execute without setting planning variables I have
[Exception in thread "main" java.lang.NullPointerException]
