Interesting and very frustrating. It seems there are potentially other flags that could get passed already that would cause the same kind of failure.

This really is not something that tests should need to be aware of. And to be honest the fact that -Dcompiler.jdk even exists and solves this problem is somewhat of a fortuitous accident (it was added way, way back to allow testing with JRE's that did not contain all the JDK tools).

Doe a static JDK image not implicitly contain all the tools, if you invoked them directly rather than via their custom launchers? Or are they stripped out unless explicitly created as part of that image? I'm just wondering if there is a more direct way for JdkToolFinder to work with static images?
