Every major Jakarta EE release tends to have a defining theme. Jakarta EE 11 was about modernization: a new baseline with Java 17, forward compatibility with Java 21, and a decisive cleanup of long-standing technical debt. Jakarta EE 12 builds directly on that momentum, but its direction is different. This release is less about removing the past and more about aligning the future.
Jakarta EE 12 is best understood as the Data Age of enterprise Java.
