[jacorb-developer] Removing a servant from JacORB after calling "servant_to_reference"

[Andrew Bourgeois]

Hi Phil,
Hi Nick,

@Phil: It looks like your solution does the trick. It'll need more testing,
but a quick test shows (in JProfiler) that the objects are gone. Other
objects that have the same problem are still there, so the app didn't
break. Thanks a lot.

@Nick: It's the server that generates servant objects and generates an IOR
so that the client can use it to connect to the server. I can't test the
new version 3 (beta) at work, but I will at home later this week.

Best regards

Andrew
