java.lang.NullPointerException at org.springframework.test.web.servlet.result.MockMvcResultHandlers.<clinit>(MockM‌​vcResultHandlers.java:44)

is thrown when making use of MockMvcResultHandlers.print() in one of my JUnit 4.11 tests.

Line 44 of MockM‌​vcResultHandlers looks like this:
private static final Log logger = LogFactory.getLog(MockMvcResultHandlers.class.getPackage().getName());

I've confirmed that it is the getPackage() call that is returning null.

From what I've read, it might be due to how the class loading works with the maven-surefire-plugin when a forkCount of 0. Unfortunately, I can't update to 1 to verify if that will help getPackage() not return null.

Class.getPackage() is known to be unreliable in certain environments, so we're generally trying to avoid it. I've fixed that logger initialization for 4.2.4. Thanks for raising this!
