StoryRunner failure strategy is not set when running before or after stories steps in multiple threads

I got following exception when building attached project (mvn clean install):

-------------------------------------------------------------------------------
Test set: pl.mmadej.jbehave.JBehaveStoriesTest

Please investigate. This error happens with jbehave 3.4. When I'm using 3.3.2 everything looks ok.
Internally there is NPE in StoryRunner:76 – currentStrategy.get().handleFailure(storyFailure.get());
currentStrategy.get() returns null.

Please investigate.
Thanks in advance for your help
