Uwe Schindler commented on LUCENE-6238:
---------------------------------------
Thanks Robert. I will later try and run everything on windows to ensure all is
fine.
Your recent patch (LUCENE-6292) added read access to "/dev/urandom", maybe we
should also add this here to test it thoroughly (currently it falls back to
backup strategy for getting a random seed)? Or is this not applicable for tests
because it always uses {{-Dtest.seed}} while testing so it never tries to open
that file?

> This is overly permissive:
> {noformat}
> // Basic permissions needed for Lucene to work:
> permission java.util.PropertyPermission "*", "read,write";
> permission java.lang.reflect.ReflectPermission "*";
> permission java.lang.RuntimePermission "*";
> {noformat}
> Because of various BS like unsafe-hacks (only mmap seems to do it properly),
> this means effectively you cannot use lucene with SM today, without allowing
> SM itself to just be disabled with reflection.
> This is easy to fix.
