We are using Picketlink 2.5.2.Final for Federated Identity Management withi=
n Tomcat 7.0.42. When the user invokes a request without being authenticate=
d the FormAuthenticator will save the request into the session, issue the a=
uthentication request and then restore the original request.
However, the saveRequest method in FormAuthenticator does not save the requ=
est body. Debugging into Tomcat we found out that the while loop which writ=
es the body is stepped over because is.read() returns -1.

        InputStream is =3D request.getInputStream();

        while ( (bytesRead =3D is.read(buffer) ) >=3D 0) {
            body.append(buffer, 0, bytesRead);
        }

Can anybody give a hint why the request inputstream can't be read?
Thank you!
