Description Ori Marko CLA 2018-12-17 06:17:09 EST 
You cannot create arrays of parameterized types, so below code can't be parameterized

ArrayList<Integer>[] list = new ArrayList[1];

But Eclipse shows a warning

Type safety: The expression of type ArrayList[] needs unchecked conversion to conform to ArrayList<Integer>[]

And also shows suggestion Infer Generic Type Arguments which does nothing when submitted.

I suggest Infer Generic Type shouldn't be suggested in this case

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.

Problem still occurs, and I still want the feature (not suggesting if nothing can be changed)
