I had so many interesting new things to talk about in the summary of Jakarta Persistence 3.2 that I forgot to mention an important thing we’re taking away.
Cross-posted from Substack.
One of the most important experiences of my career was working with Linda DeMichiel from Sun, Mike Keith from TopLink, Evan Ireland from Sybase, and others, to design and write the first version of the Java Persistence specification.
Today this technology enjoys broad acceptance, even among former critics. But in recent years, despite a name change to Jakarta Persistence, the spec has not evolved rapidly. Not until now, that is. Over the last year or so, Lukas Jungmann from Oracle and I have been working rather hard to bring you the biggest release of Persistence in a long time.
This post will concentrate on new features we’ve added to Jakarta Persistence. It’s worth mentioning that quite a lot of work has gone into clarifying the semantics of existing features, and rewriting certain sections of the spec for clarity and readability. This is an ongoing effort. The spec is more than 500 pages in length; rewriting such text without accidentally changing its meaning is a slow and painstaking process.
In a previous post I talked about Jakarta Data. Alignment of the two specifications has been a further priority.
