Symptoms

A JDBC Thin connection needs to use TLS v1.2.
When connecting to a database using Grid Infrastructure 12.2,
the JDBC connection fails unless the client's JDBC connection properties are modified to include:

connprops.setProperty("oracle.net.ssl_version","1.2");

Meanwhile, SQL*Plus is able to successfully connect using TLS v1.2.

Changes

Grid Infrastructure was upgraded from 12.1 to 12.2.
JDBC Thin client had Patch 19030178 applied.
