Description mclaborn 2016-07-22 17:59:54 UTC 
Product Version = NetBeans IDE Dev (Build 201607210002)
Operating System = Linux version 4.4.0-31-generic running on amd64
Java; VM; Vendor = 1.8.0_102
Runtime = Java HotSpot(TM) 64-Bit Server VM 25.102-b14

Reproducibility: Happens every time

In the code snippet below, the last line is flagged as an error in the Java editor in this build.  The error is 

Error: incompatible types: ArrayList<CAP#1> cannot be converted to ArrayList<IOrderItem>
  where CAP#1 is a fresh type-variable:
    CAP#1 extends IOrderItem from capture of ? extends IOrderItem

No error is reported during a clean + build.
This was not a problem in NB 8.1

Oops - here is the code snippet.

  public DialogSelectShipWeek(OE2 a_owner, Customer a_customer, Collection<? extends IOrderItem> a_items) {
    super(a_owner, true);
    ArrayList<IOrderItem> items = new ArrayList<>(a_items);
Comment 3 Dusan Balek 2016-09-12 14:29:53 UTC 
Unfortunately, I cannot reproduce the problem in the current dev build. If you are still able to reproduce the problem, could you please create a simple test project and attach it to the issue? Thanks.
