A ClassNotFoundException would mean that you are missing the junit
dependency to JUnit4 bundle.
A NoClassDefFoundError without a ClassNotFound may be an incompatible
version of Java.
Seek for the cause of this NoClassDefFound error and you'll get a very
helpful hint.

Which version of Java are you using? What is the minimal requirement for
this JUnit class to load?
