> When running a simple "hello world" example on JDK 17, I noticed the closure cleaner tries to reflectively access the {{java.lang.String}} class, which fails due to the strong encapsulation enabled by default in JDK 17 and beyond. I don't think the closure cleaner needs to act on {{String}} at all, as it doesn't contain any inner classes. Unless there are objections, I'll provide a fix along those lines. With this change in place, I can run that example on JDK 17.
