Start with the connection call shown at Main.java:26 and the CLIENT_PLUGIN_AUTH stack trace. Reproduce the failure with the higher and lower mysql-connector-java versions mentioned, then determine the compatibility boundary and affected connection path. Done means the connection succeeds with the supported version or the incompatibility is clearly documented.
