    Description

      The Admin -> Cloud -> ZK Status page in Solr 8.6.0 does not show any data except for the error message "null". I get the following exception in solr.log:

      It seems that ZkDynamicConfig.java fails to parse my zknode's /zookeeper/config. Here's the content:

      server.1=dev-confluentzoo2014.sol-osl01.host.example.com:7795:7796:participant
server.2=dev-confluentzoo2015.sol-osl01.host.example.com:7795:7796:participant
server.3=dev-confluentzoo2016.sol-osl01.host.example.com:7795:7796:participant
version=0

      This problem does not occur in 8.5.x. Our zookeeper is at v3.5.7.
