A sixth feature, ahead-of-time (AOT) code compilation, has been proposed for JDK 28. Java Development Kit 28 is a non-LTS (Long-Term Support) or “feature release” of standard Java due in March 2027.
Ahead-of-time code compilation would improve Java application startup and warmup time by making optimized native code for the application instantly available when the Java Virtual Machine starts, according to the proposal. Goals of the proposal include enabling applications to achieve peak performance more quickly and enabling applications to sustain peak performance even as workloads change, without requiring any changes to the code of applications, libraries, or frameworks.
The five features previously targeted to JDK 28 include the following:
