KumuluzEE 3.8.0 released!
We are happy to announce the release of the KumuluzEE 3.8.0. The new release brings a new database connection pool implementation which improves the JTA transaction handling.
The new version of the framework includes the Agroal database connection pool, which is used with the JTA transactions. It improves transaction handling and fixes some existing problems. Non-JTA datasources still use the HikariCP connection pool. The HikariCP is wrapped in the Agroal API, the version of the HikariCP has been upped from 2.7.9 to 3.4.1 (changelog).
The new connection pool implementation brings some new configuration options, while some old ones were deprecated. The list of all available configuration properties is listed in the EeConfig wiki.
We have also included the missing integration between CDI and JTA components, which improves the propagation of JTA events.
