Hi,
This code works fine for javac:
public class Test<T> {
	private T data;
	private Test(T data){ this.data=data; }
	public static <S> Test<S> createObject(S data){
		return new Test<S>(data);
	}
	public static void main(String[] args) {
		Test<String> res=Test.createObject("Hallo");
	}
}

I also would expect the following to work:
Test<String> res=Test.<String>createObject("Hallo");

Resolved along with fix for bug 77052.
Added regression test: GenericTypeTest#test340.

Actually, this wasn't a dup.

Comment 4 Philipe Mulet

Fixed (generic static method of raw type remains generic)

I tried this out in N20041028, and the compiler no longer gives an error, but it
still gives a warning, which javac doesn't:

Type safety: The method createObject(String) belongs to the raw type Test.
References to generic type Test<T> should be parameterized

The warning disappeared today with my latest changes.
