Welcome to the seventy-eighth issue of Hashtag Jakarta EE!
Summer is here (at least for those of us located in the Northern hemisphere…) and things are slowing down a little everywhere. But, the Jakarta EE Platform project continues to check items off the list preparing for Jakarta EE 10.
In our last call, we summarized the vote we have had running on the public mailing list regarding which version of Java SE to use the base for Jakarta EE 10. The preferred selection by the community (committers and non-committers) was the one labeled “Option 1”. This option establishes Java SE 11 as the base for Jakarta EE 10. That means that the Jakarta EE APIs will be able to take advantage of up-to Java SE 11 language features and the API JARs will be compiled to Java SE 11 byte code level.
The option also states that the TCK should be able to test runtimes that are using any Java SE level of 11 and above. This is actually the most interesting part for Jakarta EE application developers. As long as the implementation of my choice is offering to run on e.g. Java SE 17, I can use all the Java SE 17 features I want in my application. The fact that the APIs are compiled with Java SE 11 and aren’t exposing any language features above 11, does not really affect me that much.
It is really a win-win since it allows more conservative organizations to stay on Java SE 11 for as long as they wish while the ones more eager to stay up-front can move on to Java SE 17 and above.
