Generic Array Creation - NOT ALLOWED?(java 5.0)

private <K, V> V[] getMapValuesAsArray(Map<K, V> map) {
V[] valueArray= new V[map.entrySet().size()];
int count=0;
for(Map.Entry<K, V> entry : map.entrySet()) {
valueArray[count] = entry.getValue();
count++;
}
return valueArray;
}

In the above code,

Why cannot the below line be allowed in java?
V[] valueArray= new V[map.entrySet().size()];

Because at compile time Java does not know what "V" is and it is, through erasure, reduced to Object. See the Generics Tutorial.

I really can not figureout , why does it need to know at compile time.

I think, if java can support, strict typing, this could be posible. (I guess).

So why not java can introduce some kind of annotation, to support strict typing at class/method level and only if that annotation is present, this kind of code snippet can be allowed.
