----------------------------------------------------------------------
I can run it on my Linux box, if it helps. It has 32 cores (64 threads),
overclocked to 4.1GHz on all cores. This is the Threadripper 3970X, nothing
less powerful than this one is suitable for working on Solr tests, unless one
has the patience of a monk ;-)
Edit: I just started a run; will report back on status soon.

> The solr-tests.policy is currently way too lenient. Its useful for tests but
> pretty worthless at defending against any attacker "for real"
> For example imagine i can execute arbitrary java-ish code:
> {code}
> Runtime.getRuntime().exec("id");
> {code}
> With a security manager enabled, I'd get an exception like this:
> java.security.AccessControlException: access denied ("java.io.FilePermission"
> "<<ALL FILES>>" "execute")
> Because the current policy is so lenient and has wildcard RuntimePermission,
> the next thing i'd try (disable security manager, then launch process) would
> happily execute:
> {code}
> System.setSecurityManager(null);Runtime.getRuntime().exec("id");
> {code}
> That's because the current wildcard permission allows
> {{RuntimePermission("setSecurityManager")}}.
> There are other variants I could use, some explained by java's docs:
> https://docs.oracle.com/javase/7/docs/api/java/lang/RuntimePermission.html
> It will take time and pain to clean up this stuff: e.g. fixing code and maybe
> even third-party dependencies, but gotta start somewhere. I think splitting
> up the wildcards is a good first step :)
