Update JavaDoc for return type of SecurityUtils.getSubject()
------------------------------------------------------------
Key: JSEC-20
URL: https://issues.apache.org/jira/browse/JSEC-20
Project: JSecurity
Issue Type: Task
Components: Documentation
Reporter: Grzegorz Borkowski
Priority: Trivial
>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?)
