You'd also need to allow:

"user.timezone", "java.rmi.server.randomIDs"

Why the randomIDs one? All tests pass without this randomIDs. we don't use RMI 
anywhere.

> 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.
