The cause of the problem is in your style:
<Font>
<CssParameter name="font-size">0</CssParameter>
</Font>
Font size zero? Anyways, the renderer should defend itself
from this kind of abuse and just skip rendering labels.
http://jira.codehaus.org/browse/GEOT-2579
Also, the style as build does not validate, not even against
the modified GeoServer schema. The version I included at the
bottom of this mail does validate and renderer without
entering in an infinite loop.
Cheers
Andrea
