Error while creating mysql connection using non-interceptor mode

When we add libraries and follow the steps mentioned in the non-interceptor mode as per the ReadMe file, we are getting the below connection error. Please advice. Also, does it work for JDBC connection pool?

java.sql.SQLException: Driver:com.mysql.jdbc.Driver@20124626 returned null for URL:jdbc:tracing:mysql://localhost:3306/db_test?traceWithActiveSpanOnly=true

Start with the README's non-interceptor mode instructions and the JDBC connection setup described in the report. Reproduce the failing jdbc:tracing:mysql URL through the Tomcat JDBC pool, then determine whether pooled connections are supported and document or correct the behavior so the connection succeeds without the reported SQLException.
