[tor-commits] [metrics-web/master] Fix two issues found using metrics-test.



commit 5d98d4806e01169f226bace3fc095298844d4427
Author: Karsten Loesing <karsten.loesing@xxxxxxx>
Date:   Mon Sep 16 16:29:10 2019 +0200

    Fix two issues found using metrics-test.
    
     - Make unit test locale-independent, similar to Onionoo's 860228c.
    
     - Replace deprecated method Class.newInstance().
