Digy commented on LUCENENET-357:

> Initially I had to remove a few references to the Sys Environment to get it to work. However now it fails use of the 'Weak Hashtable' - any reference to a 'weak[something]' will fail with a security exception. The issue only happens when returning sorted results.
> As an example here's the web.config modified trust file I'm being forced to use on Mosso (Rackspace cloud)
