------------------------------------------
Summary: Default value is 0 instead of null for Integer properties
Key: BEANUTILS-412

Project: Commons BeanUtils
Issue Type: Bug
Components: Locale BeanUtils / Converters
Affects Versions: 1.8.3
Reporter: Laurent Kloetzer
Fix For: 1.8.4
See the following test to see the problem and its solution.
public class Test {
/**
* @param args
* @throws InvocationTargetException
* @throws IllegalAccessException
*/
public static void main(String[] args) throws IllegalAccessException,
InvocationTargetException {
test(false);
test(true);
}
protected static void test(boolean withFix) throws
IllegalAccessException, InvocationTargetException {
Thing t1 = new Thing();
t1.valInt = 1;
t1.valInteger = 2;
Thing t2 = new Thing();
t2.valInt = 0;
t2.valInteger = null;
Thing t3 = new Thing();
Thing t4 = new Thing();
System.out.println(t2);
System.out.println(t1);
if (withFix) {
IntegerConverter ic = new IntegerConverter(null);
BeanUtilsBean.getInstance().getConvertUtils().register(ic, Integer.class);
}
BeanUtilsBean.getInstance().copyProperties(t3, t1);
BeanUtilsBean.getInstance().copyProperties(t4, t2);
System.out.println(t4);
