The problematic resource seems to be the theme.ecss, which translates into something similar to the following in the generated HTML:

<link type="text/css" rel="stylesheet" href="/myproject/rfRes/theme.ecss.seam?db=eAHb1WuhCAAFJAGh" />


Version-Release number of selected component (if applicable):
jboss-seam-2.3.0.Final-redhat-1

How reproducible:
Always

Steps to Reproduce:
1. Use seam-gen to generate a default WAR project
2. explode the project into EAP6.0.0
3. Clear cache in Firefox (as it won't load the problematic CSS resource if it already have it in cache)
4. Open http://127.0.0.1:8080/myproject/home.seam
  
Actual results:
The aforementioned warnings appear in the logs.

Expected results:
No errors or warnings should appear in the logs
