I will need an example test; otherwise I've no idea how to produce the NPE.

public class TestClass
{
@Mocked ClassToMock mockedInstance;
@test
public void testMethodToTest()
{
ClassToTest classToTestInstance = new ClassToTest();
Object someObject = new Object();
new Expectations()
{
mockedInstance.methodToMock();//NullPointerException
returns(someObject);
}
}
}
Some test cases pass but some test cases throw exception.

Running the example test, there is no NullPointerException for me...

Yes. But in my other code there is NullPointerException. That is proprietary code. So I can not post that code.
Here is the stack trace

Thank you. This issue is resolved. But some other test cases started failing when I downloaded this 577b334 code. Cases which has result = new MyException() in Expectations() are not working properly. Method which I mocked to throw MyException is not throwing Exception.

Mocked instance throws NullPointerException in Expectations() with JMockit 1.12 but it runs successfully with JMockit 1.11.
