We've discussed about them in #32210, and we've reached the conclusion to add `--enable-preview` into the argument of `createLimitedTestJavaProcessBuilder`. LingeredApp should be kicked as an another process because the test have to attach it to test SA features. It is out of control from jtreg. Thus we need to add `--enable-preview` if needs. As you know SA is like a debugger, so command line arguments of debuggee (LingeredApp) might be different from jtreg test. ------------- PR Comment: https://git.openjdk.org/jdk/pull/32262#issuecomment-5230986736
