Grzegorz Borkowski commented on JSEC-20:
----------------------------------------
>From what I see now in SecurityUtils code, I see that this method will return
>null if no SecurityManager or Subject is registered in ThreadContext or as
>VM-singleton SecurityManager - so probably this information should be put in
>javadoc.
> Update JavaDoc for return type of SecurityUtils.getSubject()

> From JavaDoc for SecurityUtils.getSubject() it is not clear what returns
> this method if nobody is logged in. Does it return null? or some default
> Subject? From Subject class documentation (getPrincipal method) I would
> expect that SecurityUtils.getSubject() returns some default Subject, but
> simple tests shows that it is not true - it returns null.
> So I would change it like this:
> @return the currently accessible <tt>Subject</tt> accessible to the calling
> code or null if .... (actually when?)
