NullPointerException with JUnit 4.12

When using JUnit 4.12 a problem appears when JBehave is trying to build the reporting :

The nullpointer is caused by following line:

JunitReportingRunner:171

private void initRootDescription()

Unknown macro: { rootDescription = Description .createSuiteDescription(configurableEmbedder.getClass()); rootDescription.getChildren().addAll(storyDescriptions); }

rootDescription.getChildren returns a new array list of children, so doing addAll does not actually add the children to the actual list of Description
Description class does offer a method addChild, using this method would solve this issue
