> We've experienced marshalling errors occasionally when passing a java.util.Date back to JavaScript there are lots of threads issuing requests.   This has been tracked down to the server producing an XML response that has garbage/incorrect values in the <date> element.
> The problem is caused by the static 'df' variable in org.jboss.seam.remoting.wrapper.DateWrapper, which is a SimpleDateFormat.   In a highly concurrent environment, calls to this SimpleDateFormat will overlap, and since SimpleDateFormat is not thread-safe, it will yield strange results.
