Partial mocking of global MockUps causes NullPointerException

[borisbrodski]

Reproduction steps:

Create following files:

• Tool.java

public class Tool {
    public void doIt() {
    }
}

• ToolMock.java:

import mockit.Invocation;
import mockit.Mock;
import mockit.MockUp;

public class ToolMock extends MockUp<Tool>{
    @Mock
    public void doIt(Invocation e){
    }
}

• jmockit.properties:

mocks=test.ToolMock

• Test1.java:

import mockit.NonStrictExpectations;

import org.junit.Test;

public class Test1 {
    @Test
    public void test1() {
        new NonStrictExpectations(Tool.class) {{
        }};
    }

    @Test
    public void test2() {
        new Tool().doIt();
    }
}

Run Test1.

Result:

• Test1.test1 OK
• Test1.test2 FAILS. Exception:

java.lang.NullPointerException
    at test.Tool.doIt(Tool.java)
    at test.Test1.test2(Test1.java:16)

Also all consequent tests getting the same NullPointerException, if Tool class get used.

Well spotted, thanks! It will be fixed for release 1.12.
