EasyMock的anyObject使用时候的问题

原因是： EasyMock的anyObject虽然是个模版方法，但是返回了一个null，这个在java自动类型转换的时候就回报异常。

public static <T> T anyObject(final Class<T> clazz) {
        reportMatcher(Any.ANY);
        return null;
    }

关于这个问题，我已经给EasyMock报了bug了，bug链接地址：
https://jira.codehaus.org/browse/EASYMOCK-114

下面是复现代码：

import java.util.List;

public interface IService {
	List<String> query(String key, int... startAndPerPages);
}

import java.util.List;
import java.util.Collections;

public class ServiceImpl implements IService{

	@SuppressWarnings("unchecked")
	public List<String> query(String key, int... startAndPerPages) {
		return Collections.EMPTY_LIST;
	}

}

import java.util.List;

public class ClientService {
	private IService depenService;
	
	public List<String> query(String key, int... startAndPerPages) {
		List<String> rets = depenService.query(key, startAndPerPages);
		rets.add("aaaa");
		return rets;
	}

	public void setDepenService(IService depenService) {
		this.depenService = depenService;
	}
}

import java.util.ArrayList;
import java.util.List;

import org.easymock.EasyMock;
import org.junit.Before;
import org.junit.Test;

public class ClientServiceTest {
	@Test
	public void query_page_error(){
	    ClientService clientService = new ClientService();
		IService mockService = EasyMock.createMock(IService.class);
		EasyMock.expect(mockService.query(EasyMock.anyObject(String.class),
				EasyMock.anyObject(Integer.class),EasyMock.anyObject(Integer.class)));
		
		EasyMock.replay(mockService);
		clientService.setDepenService(mockService);
		
		String key = "test";
		int startPage = 1;
		int recordsPerPage = 10;
		
		clientService.query(key, startPage,recordsPerPage);
		
		EasyMock.verify(mockService);
	}
	
	@Test
	public void query_page_correct(){
		ClientService clientService = new ClientService();
		 
		List<String> rets = new ArrayList<String>();
		
		IService mockService = EasyMock.createMock(IService.class);
		EasyMock.expect(mockService.query(EasyMock.anyObject(String.class),
				EasyMock.anyInt(),EasyMock.anyInt()))
				.andReturn(rets);
		
		EasyMock.replay(mockService);
		clientService.setDepenService(mockService);
		
		String key = "test";
		int startPage = 1;
		int recordsPerPage = 10;
		
		clientService.query(key, startPage,recordsPerPage);
		
		EasyMock.verify(mockService);
	}
}

错误现象，第一个报NullPointException，
