The parameter value for getConnection is:
jdbc:mariadb://synology215:3307/mydatabase?user=user&password=password&useSSL=false&allowPublicKeyRetrieval=true&sslMode=DISABLED&pool&minPoolSize=2&connectTimeout=1000

Version 2.7.0 works OK. I've not tried 3.0.0.
This is similar to CONJ-871 but the environment is plain vanilla Java, desktop application.
