here's the problem persisting the TimeZone:
-------------------------------------
@Persistent(defaultFetchGroup="true")
private TimeZone timezone;
-------------------------------------
-------------------------------------
java.lang.IllegalArgumentException: timezone:
sun.util.calendar.ZoneInfo is not a supported property type.
