RickyMa commented on RANGER-2895:
---------------------------------

Due to EclispseLink compatibility issue, this time we replace c3p0 with HikariCP and upgrade MySQL connector only.

> We should replace c3p0 with [HikariCP|[https://github.com/brettwooldridge/HikariCP]]. HikariCP is much faster and less error prone. HikariCP is more popular with 13.2k+ stars on its github. There were no more new commits since Nov 18, 2019 in [c3p0|[https://github.com/swaldman/c3p0/commits/master]].
> [MySQL connector|[https://github.com/mysql/mysql-connector-j]] should be upgraded to the latest stable versions as well to include many essential bugfixes.
