The problem seems to be my locale settings (IT).
According to this http://paolobacco.blogspot.it/2012/03/jaxb-xjc-javalangillegalargumentexcepti.html jaxb-xjc does not support locale different from US.
does this still occur with new portage (that sets ebuild locale to C)?
Title Language of messages in emerge logs and output
Author Andreas K. Huettel <email@example.com>
As of today, messages and logs of emerge do not use the system
locale anymore but default to English. The intention behind this
is to ease the work of bug wranglers and package maintainers,
who may have a hard time reading build logs in foreign
languages. This change only affects the language of messages
in emerge output, nothing else.
If you really want to have e.g. localized compiler error messages
in your builds, set LC_MESSAGES in your /etc/portage/make.conf.
Note that submitting localized build logs to the Gentoo Bugzilla
is discouraged. If maintainers are unable to translate the
necessary information from the build log, your bug may be closed
as NEEDINFO and you may be asked to re-open it submitting an
English build log  before any further action can be taken.
