Got the following exception when trying to run with JUnit 4.5 (it was existing project to which I added lamda-behave):
java.lang.NoSuchFieldError: NULL
at org.junit.runners.ParentRunner.<init>(ParentRunner.java:57)
at org.junit.internal.requests.ClassRequest.buildRunner(ClassRequest.java:33)
at org.junit.internal.requests.ClassRequest.getRunner(ClassRequest.java:28)
Works fine with JUnit 4.11. Created this issue mostly to "document" the exception.
