[jira] [Commented] (LUCENE-6238) minimize tests.policy

["Ryan Ernst (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-6238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14336166#comment-14336166 ] 

Ryan Ernst commented on LUCENE-6238:
------------------------------------

+1

For the properties permission, it looks like the end quote of the permissions is in the wrong place?
{{"read",write;}} should be {{"read,write";}}?

> 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.
