MySQL Failed to initialize JDBC driver 'com.mysql.cj.jdbc.Driver'

[wblangdon]

Following issue #612 we have Java 23 ok (thanks again).

I do not know if this is a Benchbase, MySQL, JDBC or CLASSPATH problem but...

When I try (with Java 23.0.2) java -jar benchbase.jar -b tpcc -c config/mysql/sample_tpcc_config.xml --create=true --load=true --execute=true it immediately fails with exit status 1 and output:

any help or guidance would be most welcome Bill
