Regression: Calling constructor for MockUp in Test results in java.lang.VerifyError for 1.9 #25
Description
Issue:
I have a mock class that extends MockUp. When running tests in JMockIt 1.9, the tests fail with java.lang.VerifyError. This is through Maven on OSX.
$ mvn --version
Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-14T09:37:52-08:00)
Maven home: /usr/local/Cellar/maven/3.2.1/libexec
Java version: 1.7.0_45, vendor: Oracle Corporation

I rolled back JMockIt to 1.8 and the tests passed again. Also, tests seem to work in IntelliJ on 1.9 with standard configuration run. Code is below.
Created a mock class that mocks org.mongojack.DBCursor
import mockit.Mock;
import mockit.MockUp;
import org.mongojack.DBCursor;
import org.mongojack.JacksonDBCollection;
import java.util.List;
public class DBCursorMock<T> extends MockUp<DBCursor<T>> {
private List<T> items = null;
public DBCursorMock (List<T> items) {
this.items = items;
}
@Mock
public void $init (JacksonDBCollection<T, ?> jacksonDBCollection,
com.mongodb.DBCursor cursor) {
}
@Mock
public List<T> toArray () {
return items;
}
}
Class is called in test like so:
JacksonDBCollectionMock<User, ObjectId> collection = new JacksonDBCollectionMock<>();
collection.setDBObjectItems(userList);
new DBCursorMock<>(userList);
(Note: JacksonDBCollectionMock is another mock that does not have an $init method.)
