What happened?

When using a host-less jdbc string as jdbc:tc:mysql:8.0.36:///my_database?useConfigs=maxPerformance&characterEncoding=utf8&useSSL=false as suggested in the examples [1], the database name is not correctly extracted and it defaults to test. Adding any random host:port allows the database name to be extracted correctly (e.g. jdbc:tc:mysql:8.0.36://foobar:42424242/my_database )

The regex that extracts the database name does not support host-less jdbc urls "([^:]+)(:([0-9]+))?/([^\\\\?]+) as it tries to extract it from the dbHostString field that in case of a host-less jdbc string is /database_name.
