Release Notes for MariaDB Connector/J 3.0.10


MariaDB Connector/J is a lightweight JDBC driver (Type 4) for building applications on top of MariaDB database products with Java 8, Java 11, and Java 17.

This release is compatible with JDBC 4.2.

MariaDB Connector/J 3.0.10 was released on 2023-01-11. This release is of General Availability (GA) maturity.

Issues Fixed

  • When Connector/J performs an SSL Handshake, it sets the CLIENT_SSL capability flag in the SSL Connection Request Packet, but not in the Handshake Response Packet. (CONJ-1023)

    • In previous releases, the CLIENT_SSL capability flag is not required to be set in the Handshake Response Packet, so this issue is only noticed when inspecting the network traffic.

    • Starting with this release, Connector/J sets the CLIENT_SSL capability flag in both the SSL Connection Request Packet and in the Handshake Response Packet.

  • When running the client on a machine with a non-fixed-offset timezone, the timezone=auto JDBC option fails with the error: (CONJ-1026)

    ``Setting configured timezone 'auto' fail on server.``
  • When mapping the deprecated arguments useSsl, trustServerCertificate, and disableSslHostnameVerification to the new sslMode argument, there can be issues due to different handling of case sensitivity in code that handles argument names. (CONJ-1032)


MariaDB Connector/J 3.0 has been superseded by MariaDB Connector/J 3.3, which is fully compatible with MariaDB Connector/J 3.0. For upgrade instructions:
