Issue

• JSF application's response charset enconding was changed after migrating to EAP 6.1.0 onwards

• I have a JSF application which specify <?xml version="1.0" encoding="Windows-31J" ?> in each page. However, charset encoding in JSF application's Response Content-Type header becomes different between in EAP 6.0.x and in EAP 6.1.0 onwards.

  • In EAP 6.0.x, Content-Type:text/html;charset=Windows-31J was returned:

    $ curl -v http://localhost:8080/example/faces/example.xhtml
    > GET /example/faces/example.xhtml HTTP/1.1
    > User-Agent: curl/7.29.0
    > Host: localhost:8080
    > Accept: */*
    > 
    < HTTP/1.1 200 OK
    < Server: Apache-Coyote/1.1
    < ...
    < Content-Type: text/html;charset=Windows-31J
    < ...
    

  • In EAP 6.1 onwards, Content-Type:text/html;charset=UTF-8 was returned:

    $ curl -v http://localhost:8080/example/faces/example.xhtml
    > GET /example/faces/example.xhtml HTTP/1.1
    > User-Agent: curl/7.29.0
    > Host: localhost:8080
    > Accept: */*
    > 
    < HTTP/1.1 200 OK
    < Server: Apache-Coyote/1.1
    < ...
    < Content-Type: text/html;charset=UTF-8
    < ...
    

  What caused this behavior change? How can I specify charset in JSF application?
