The application runs on a Heroku server, it is on Java 1.6, using Jetty Version 7.6.16.v20140903 I also found this (seemingly) related bug: <https://jira.codehaus.org/browse/JETTY-1423,> https://jira.codehaus.org/browse/JETTY-1423 , however, since I am using Jetty 1.6 I am not using an affected version. Any help or insight into what may be causing this issue would be appreciated.
