The protocol and cipher were both set to "any".

We determined that this was selecting TLSv1.3, which was only recently 
introduced as an available protocol in Oracle's JDK8.  If TLSv1.2 is specified 
instead of "any" things work fine.

The problem does not occur with Geode v1.13 unless you request TLSv1.3 with 
Oracle JDK8.  We were using 1.8.0_261.
