OpenJDK
David Delabassee, director of Java developer relations at Oracle, has announced a change in annotation processing. The OpenJDK team is considering disabling default implicit annotation processing in a future release of OpenJDK. This is due to implicit annotation proceeding when there are no annotation processing configuration options. As of JDK 21 Build 29 and JDK 22 Build 4, the javac utility will print a note (as shown below) if implicit annotation processing is being used.
Annotation processing is enabled because one or more processors were
found on the class path. A future release of javac may disable
annotation processing unless at least one processor is specified by
name (-processor), or a search path is specified (--processor-path,
--processor-module-path), or annotation processing is enabled
explicitly (-proc:only, -proc:full).
Use -Xlint:-options to suppress this message.
Use -proc:none to disable annotation processing.
