When Objects involved in methods are very hughe and nested, jboss goes into and endless loop when deployment

When deploying a simple web-service that returns a hughe and nested tree, in my example (near 300 classes),
jboss generates the JAXB, and starts and endless loop when running JBossXSModel.

Found a similar case in forums where they are trying to return an HTML element obtained,
form mapping the xhtml xsd (see the jforum reference)

The log in jboss shows:

A similar last line is repeated forever and ever (it filled 20Gb of log in my computer).

I've tried to create a smaller example, up to 10 classes, all nested etc., but still cannot reproduce the
problem, I keep on trying.
