We enabled running jtreg tests on static-jdk in GHA (https://github.com/openjdk/jdk/commit/16d45511342c32ac8e8f72fb68dc21ce13339dbe). It sets `JDK_UNDER_TEST=<static-jdk-path>`, `JDK_FOR_COMPILE=<regular-jdk-path>` and `extra-problem-lists` with .github/workflows/test.yml to run tests on static-jdk. Probably relatively easy to setup with tired testing as well.
