    Description

      The newFrames are polled using the same pattern described in UNDERTOW-1620:

                  while (!newFrames.isEmpty()) {
                S frame = newFrames.poll();
                frame.preWrite();
                ...

      This could result in a NPE if run in parallel with markWritesBroken, that invokes newFrames.clear().

This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
