You'll probably want to look into your Java Security Policy settings
as that is what causes this error. You can see default security policy
included in the Solr distribution here:
https://github.com/apache/solr/blob/b9100ba775defbed5114dd92526382047ce611dc/solr/server/etc/security.policy#L4.
You'll want to make sure the right properties are being set for your
Solr data directory to ensure Solr has file permissions to that
directory.
