Description Pavel Krupets CLA 2004-06-25 06:05:18 EDT 
I've got next static function:
public static Collection<IAttribute> createCollection(Attributes atts) {}

I invoke it like this:
Collection<IAttribute> atts = Attribute.createCollection(...);

Warning message:
Unsafe type operation: should not assign expression of raw type Collection to 
type Collection<IAttribute>. References to generic type Collection<E> should be 
parameterized.

Sorry if it's my mistake. I couldn't find any generics references guides, etc.
Comment 1 Philipe Mulet CLA 2004-07-05 18:56:01 EDT 
Cannot reproduce on following testcase with latest HEAD contents:

import java.util.Collection;
public class X {
  public static void main(String[] args) {
     Collection<IAttribute> atts = Attribute.createCollection(null);
  }
}
interface IAttribute {}

class Attribute implements IAttribute {
  public static Collection<IAttribute> createCollection(Attribute atts) {
    return null;
  }
}
Comment 2 Philipe Mulet CLA 2004-07-06 06:17:08 EDT 
Cannot reproduce with Cheetah06 either.

Please reopen with steps to reproduce.

Closing as never reproduced in a long time
Comment 4 Denis Roy CLA 2009-08-30 02:05:17 EDT 
As of now 'LATER' and 'REMIND' resolutions are no longer supported.
Please reopen this bug if it is still valid for you.
