Description of problem:
JQuery javascript is invoked fine with the exo.product.developing=true parameter, but doesn't work without it.

How to reproduce:
Deploy the attached war file. It contains sample skin extended with two javascript file: jquery and test javascript file. Those files are defined in the gatein-resources.xml file. In the test javascript file, the alert is executed from the jquery environment. If you start the EPP with -Dexo.product.developing=true parameter, everything works as expected, but if you avoid the parameter, you won't be even able to click on the Sign in link (because of javascript errors).

Note: The javascript is executed (if dev parameter == true) even if the skin is not the current skin.
