What steps will reproduce the problem?
Try to run the following test case:

package com.gu.r2.perftest.cifurlmapper;

import org.junit.Test;
import org.mockito.Mockito;

public class MockitoTest {

    @Test
    public void shouldWork() {
        MyClass myClass = Mockito.mock(MyClass.class);
        myClass.varArgs("");        
        Mockito.verify(myClass).varArgs((String[]) Mockito.anyObject());

    }       
    public class MyClass {      
        public void varArgs(String... args) {

        }       
    }

}

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
1.2

Please provide any additional information below.
When changing the signature to varArgs(String[] args) it works fine.

Best,
Felix

Using the current version you can fix the problem by changing following:
Mockito.verify(myClass).varArgs((String[]) Mockito.anyObject());

Into this:
Mockito.verify(myClass).varArgs((String) Mockito.anyObject());

The bug is fixed in trunk.
