pages.xml expires attribute : invalid Expires HTTP header with french JVM default locale
----------------------------------------------------------------------------------------

                 Key: JBSEAM-4502
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-4502
             Project: Seam
          Issue Type: Bug
          Components: JSF Integration
    Affects Versions: 2.1.0.SP1
            Reporter: Gonzalez Adrian

Hello, I'm using expires attribute in pages.xml :
<page view-id="/js/global.jspx" expires="846000">
	<header name="Cache-control" value="max-age=864000"/>
</page>

I'm running with a French OS (default locale french).

When using firebug, I see the following HTTP header value :
Expires	sam., 19 déc. 2009 13:06:38 CET

This syntax is invalid (http://www.ietf.org/rfc/rfc0822.txt - section 5.1.  SYNTAX).

Just changing the following line of code in Page.java) corrects the bug :
Change :
SimpleDateFormat format = new SimpleDateFormat(RFC_1123_DATE);
With :
SimpleDateFormat format = new SimpleDateFormat(RFC_1123_DATE, Locale.ENGLISH);

And produces the expected output : 
Expires	Sat, 19 Dec 2009 09:39:48 CET
