Description

While I can see some failures of this test in the past, they weren't frequent and were usually things like port bindings (maybe SOLR-13871) or timeouts. I've started this failure in Jenkins (and locally) frequently:

Build: https://jenkins.thetaphi.de/job/Lucene-Solr-master-MacOSX/5410/
Java: 64bit/jdk-13 -XX:-UseCompressedOops -XX:+UseParallelGC

2 tests failed.
FAILED:  org.apache.solr.cloud.SyncSliceTest.test

Error Message:
expected:<5> but was:<4>

Stack Trace:
java.lang.AssertionError: expected:<5> but was:<4>

This is likely a regression
