Description

We introduced a broken behavior that leaks memory in DWPTDeleteQueue recently (LUCENE-9304) The line here tries to be smart and even adds a comment that the current impl is safe but it isn't if you reference a final member in a lambda it references this which holds on to the object. I think we need to do a quick 8.6.2 for this.
