Hello,

I have a shutdown() method as part of a server implementation:

void
MyServer_impl::shutdown()
{
   rootGroup_->_dispose();
   ...
}

which also invokes impl_shutdown() on the Boa using a separate thread, per David Riddoch's
method suggestion.

However, the client that is invoking the shutdown request gets a INV_OBJREF exception upon
invoking this method.
Funny thing is, if I change

rootGroup_->dispose();

to

delete rootGroup_;

It works fine.  Now, this goes against the rule that server object implementations that
are created with "new" should be _dispose()'d, and not deleted.  So I am not comfortable
with this solution.
It seems that the obj reference is OK in this context, because the client was able to
issue a method call to the server a previous to the shutdown() using the same reference,
without problems.

Thanks

Rob
