+
+The support of the Eclipse E4 Platform Dependency Injector for annotations from the <code>javax.inject</code> and <code>javax.annotation</code> package is deprecated
+and scheduled to be disabled by default after the December 2025 release.
+The eventual removal of support for these <code>javax</code> annotations will happen at any time after the December 2025 release without any further prior notice,
+whenever maintaining it is no longer feasible or hinders other development.
+<p>
+Processing of <code>javax</code> annotations can be explicitly disabled for an application by specifying the VM property <code>-Declipse.e4.inject.javax.disabled=true</code>
+and explicitly enabled by specifying <code>-Declipse.e4.inject.javax.disabled=false</code>.
