 Review comment:
   Hadoop generates filename ids with `String.format` without any Locale set 
and then uses regex to try to match it. This fails on locales 
`th-TH-u-nu-thai-x-lvariant-TH` and `hi-IN`. This check matches what Hadoop is 
doing to make sure there is a match.

   Currently certain locales like "ja-JP-u-ca-japanese-x-lvariant-JP" cause

   This file is copied directly from Apache Hadoop to allow integration tests 
to run under Jetty 9.4.
   
   I couldn't find a way to get the shaded Hadoop dependencies (new in Hadoop 
3) to work since they shaded too much (like javax.servlet). This made our 
integration with hadoop-auth break.
   
   I have no idea if copying HttpServer2 in here will break other things. I 
tested with JDK 8 and so far this looks good.
