Paul Elschot commented on LUCENE-6373:
--------------------------------------
I'm posting this because it seems to be almost there, I'll have very little
time in the upcoming weeks, and to show that the asserting spans of LUCENE-6411
nicely catch this.
The patch includes the use of DisiPriorityQueue<Scorer> instead of
ScorerPriorityQueue, otherwise there are no changes in the class hierarchy
(DocIdSetIterator, DisiWrapper) compared to the previous patch.
The stack trace for the failing test is:
{code}
