One variable, I recently upgraded to Java 9. I get slightly different

I'm with Erick on this. These are REALLY weird errors. The stacktraces
for the errors are entirely in ZooKeeper and Java code, not Solr code.
The log for Java 9 does have an entry that mentions Solr classes, but
that's a disconnect after the error, not part of the error.
Are you getting any corresponding log messages in the ZK server log?
The ZkCLI class is part of Solr, and does interface to ZK through Solr
internals, but ultimately it's ZK doing the work.
The ZK client that's in Solr 7.2.1 is version 3.4.10.
Thanks,
Shawn
