Hello Mauro, today I had a NullPointerException at org.jbehave.core.configuration.Configuration.doDryRun(Boolean) with JBehave beta-6.
It was because this.storyControls was null. Why don't you use storyControls().doDryRun(dryRun) instead of this.storyControls.doDryRun(dryRun)? Because the instance variable storyControls is lazy initialized in storyControls() method, so a NPE never could occur. My workaround now is first to call storyControls() method and after that doDryRun(...)
