Websphere Liberty v19 is being tested and is planned to be supported in a future release.
OpenLiberty is the open-source version of Liberty. The Pega Platform team does not test "open source" or "community editions" of application servers. “Community Editions” of application servers such as JBoss or WebSphere are in use by some clients. Customers choosing to deploy on these versions need to be self-sufficient in their support.
For sure, a lot is happening in the Java EE and the upcoming Jakarta space these days, and there will be some challenges for customers to stay current and up-to-date on supported configurations moving forward.
May I ask what the challenges are with WebSphere Liberty 19 that are preventing definitive support at this time?
