As of JDK 23, annotation processing is only run with some explicit configuration of annotation processing or with an explicit request to run annotation processing on the `javac` command line. This is a change in behavior from the existing default of looking to run annotation processing by searching the class path for processors _without_ any explicit annotation processing related options needing to
be present.

Invocations of `javac` that rely on annotation processing without any explicit annotation processing configuration will need to be updated to keep running annotation processors. In JDK 21 and 22, `javac` prints a note identifying such invocations. To preserve the old behavior, "-proc:full" can be passed to `javac`. Support for "-proc:full" has been backported to several update release trains and is also supported as of a recent version of the Maven Compiler plugin. In updated versions of the Compiler plugin, the property in question will appear as: "User Property: maven.compiler.proc" and users can configure it via `-Dmaven.compiler.proc=full` on the command-line.
