Description

public class GenericTest<T> {
private T t
public GenericTest(T t)

{ this.t=t }

public void print()

{ println t }

public static void main(String[] args)

{ GenericTest<String> t = new GenericTest<String>(new Date()) //should be thrown a exception t.print() }

}

The code: GenericTest<String> t = new GenericTest<String>(new Date()) should be thrown a exception due to Date is not a String type.
But it can run normally.

The issue also existed the following code snippet,

List<String> list = new ArrayList<String>()
list.add(new Date())
