ISession.updateSession can't be called with two different groups.

[jamoore]

btw, I can't change the group (could be "can't update session") twice for the same connection, it seems
learned it the hard way
just try to set 2 different groups and call updateSession twice
gives you that error I pasted before
also if you have created a new group

In the following block:

import omero
c = omero.client(host='localhost', port=4063)
c.ic.getProperties().setProperty(omero.constants.USERNAME, 'root')
c.ic.getProperties().setProperty(omero.constants.PASSWORD, 'ome')
session = c.createSession()
session.detachOnDestroy()

gname = "default"

try:
    sservice = c.sf.getSessionService()
    sid = c.sf.ice_getIdentity().name
    xsession = sservice.getSession(sid)
    admin = c.sf.getAdminService()
    g = admin.lookupGroup(gname)
    xsession.getDetails().setGroup(g)
    sservice.updateSession(xsession)
except:
    print "Error in first block"
else:
    sservice = c.sf.getSessionService()
    sid = c.sf.ice_getIdentity().name
    xsession = sservice.getSession(sid) # THIS THROWS!
    admin = c.sf.getAdminService()
    g = admin.lookupGroup(gname)
    xsession.getDetails().setGroup(g)
    sservice.updateSession(xsession)

the marked line throws:

Commenting it out, works. The groupExperimenterMap counts map inside of a CGLIB-based experimenter is throwing the exception.

r4508 allows the test above to pass without commenting. The bug was that a SessionContext was being bassed back through the Executor.execute method, rather than something that ProxyCleanupHandler could parse. Refactored to pass back a list of "primivites (sessions, experimenters, groups, etc.).
