Description

Elastic CI found a couple of failures in TestPriorityQueue:

java.lang.AssertionError
	at __randomizedtesting.SeedInfo.seed([7116E1C3DFA51E99:7507110B3E9E9A3]:0)
	at org.apache.lucene.util.TestPriorityQueue$IntegerQueue.lessThan(TestPriorityQueue.java:36)
	at org.apache.lucene.util.TestPriorityQueue$IntegerQueue.lessThan(TestPriorityQueue.java:28)
	at org.apache.lucene.util.PriorityQueue.upHeap(PriorityQueue.java:264)
	at org.apache.lucene.util.PriorityQueue.add(PriorityQueue.java:141)
	at org.apache.lucene.util.TestPriorityQueue.testIteratorRandom(TestPriorityQueue.java:241)

It can be reproduced with the following seed: -Dtests.seed=7116E1C3DFA51E99
It is due to https://issues.apache.org/jira/browse/LUCENE-8345 which removed the deprecated call to "new Integer" despite the fact that the queue in the tests (IntegerQueue#lessThan) does not allow to reuse Integers.
