Easymock tests fails when Object property is used

[klinki]

Hello,

we have encountered very strange bug in Easymock.
It fails to initialize @Autowired dependencies, when Object property is used.

We have following code:

Dependency

package test.easymock.bug;

import org.springframework.stereotype.Component;

@Component
public class AutowiredDependency {
  public String sayHello(String name) {
    return "Hello World, "  + name + "!";
  }
}

Service

package test.easymock.bug;

import org.springframework.beans.factory.annotation.Autowired;

public class JustTestService {
  private final Object lock = new Object();

  @Autowired
  private AutowiredDependency dependency;

  public void foo(String name) {
    if (dependency == null) {
      throw new RuntimeException("Easymock error");
    }

    dependency.sayHello(name);
  }
}

Test for service

package test.easymock.bug;

import static org.easymock.EasyMock.expect;

import com.googlecode.easymockrule.EasyMockRule;
import com.googlecode.easymockrule.StrictMock;
import com.googlecode.easymockrule.TestSubject;
import org.junit.Test;
import org.junit.Rule;

public class JustTestServiceTest {
  @Rule
  public EasyMockRule mocks = new EasyMockRule(this);

  @TestSubject
  JustTestService testedService;

  @StrictMock
  AutowiredDependency dependencyMock;

  @Test
  public void testFoo() {
    String name = "Johnny";

    expect(dependencyMock.sayHello(name)).andReturn("Hi");
    mocks.replayAll();

    testedService.foo(name);
  }
}

it fails on dependency not being correctly initialized (it is null).
BUT if we change order of properties in JustTestService, so @Autowired properties are first, it suddenly starts working.

package test.easymock.bug;

import org.springframework.beans.factory.annotation.Autowired;

public class JustTestService {
  @Autowired
  private AutowiredDependency dependency;

  private final Object lock = new Object();

  public void foo(String name) {
    if (dependency == null) {
      throw new RuntimeException("Easymock error");
    }

    dependency.sayHello(name);
  }
}

what is even more strange, if we use different type of object (Integer for example) it also works.

package test.easymock.bug;

import org.springframework.beans.factory.annotation.Autowired;

public class JustTestService {
  private final Integer lock = new Integer();

  @Autowired
  private AutowiredDependency dependency;

  public void foo(String name) {
    if (dependency == null) {
      throw new RuntimeException("Easymock error");
    }

    dependency.sayHello(name);
  }
}

It looks like a bug but I haven't had the time to have a look. Will do.
