Note that an entry such as 'B.m/C.m' in the failure chart means that the test case failed because method B.m was invoked but the test expected method C.m to be invoked. Similarly, a result such as 'AME/C.m' means that an AbstractMethodError exception was thrown but the test case expected method C.m to be invoked.

Also note that passing --dump to invoke*.Generator will dump the generated classes (for debugging purposes).
