Description

We have migrated the library from version 1.6.0 to 1.8.0 and the copyProperties() method fails when copying a java.util.Date attribute with a null value.

Here is a simple testcase :

public class Test {

	private Date date;
	
	public Date getDate() { return date;	}
	public void setDate(Date date) { this.date = date; }

	public static void main(String[] args) throws Exception {

		Test dest = new Test();
		Test source = new Test();
		BeanUtils.copyProperties(dest, source);
	}
}

As a workaround, we can do this :
ConvertUtils.register(new DateConverter(null), Date.class);

When can also use PropertyUtils.copyProperties() because in this case no conversion is required but the impact is unknown on our big application.

The problem is that there seems to be a regression between version 1.6.0 and 1.8.0.
