the TestPOJO if havn't getter&setter
just like following:
public class TestPOJO {

public String name;
public int value ;

@Override

if the TestPOJO add the getter&setter methods,this problem will be solved.

It's spend me half day to find this bug , and I hope no one will spend time in this bug.

It's very easy to test, I won't upload the testcase.

good day & good job, thanks every one!
