The type Collection is not generic; it cannot be parameterized with arguments <? extends E>

Question

I have a strange problem with Eclipse Galileo.
I set Java 1.6 as my JRE. On this line of code

List templates = new ArrayList ();

I see

Answer 1

for example:

public class AClass
{
 public HashMap myMap;
}

if I write:

public class BClass
{

private AClass aClass = new AClass();

public void test()
{

aClass.get("test");
//return Object class

}

}

but if I write:

public class BClass
{

private AClass aClass = new AClass();

public void test()
{

aClass.get("test");
//return String class

}

}
