I find that I get a ClassCastException after a redeploy when trying to
obtain a local session ejb whose interface I had stored in the http
session.  I don't know if this is correct behavior or not, but it hasn't
really been a problem for me, so I haven't worried about it.

On 3.0RC2, if it matters.
