Are you using Cyrillic characters in your URL or page? If yes, this problem could be related to code conversion as described here https://support.microsoft.com/en-us/help/925261/the-turn-off-sending-urls-as-utf-8-policy-setting-for-internet-explore
I have the same problem.
Under windows 10 only in wildfly 8,9,10 my application works correct, with wildfly 11,12 i have also that problem.
Under windows 7 in wildfly 8,9,10,11,12 my application works correct.
Now i have created a simpler application and tested it step by step.
It seems if the file faces-config.xml is in the folder WEB-INF the problem occurs
if the file is not empty, i mean if there is nothing between the tags <application>
I had the problem with windows7, I didn't solve it and just reinstalled the system to windows10, now everything is OK
