-        Yes. The JDK 11 requirement is just for running the Java language support (redhat.java) extension itself. You can still configure a different runtime <a href="command:java.helper.openUrl?%22https%3A%2F%2Fcode.visualstudio.com%2Fdocs%2Fjava%2Fjava-project%23_jdk-for-projects%22">JDK for your project</a> via the user setting <a href="command:workbench.action.openSettings?%22java.configuration.runtimes%22">"java.configuration.runtimes"</a>. The extension will pick a matching JDK to compile/run your project according to the compiler version specified by the project build file.
