by Nicolai Hess

I would like to add a fix for issue 18657 <https://pharo.fogbugz.com/f/cases/18657/Rendering-text-in-athens-is-broken> Rendering text in athens is broken But there are many changes and even new configurations of athens in its repository. Those changes aren't yet in Pharo 6. And I don't know which one to take or where to add this fix. Can people who added the latest athens changes (and configuration) please comment on what changes should go into pharo 6 thanks nicolai

Re: [Pharo-dev] [Ann] New Seamless version 0.9.0

On client object A will be represented by proxy and any message to it will produce remote interaction with object A on server side. Now what will happen if server will collect object A as garbage? Proxy on client will become broken because it will point to unexisting object on server and any message send will produce error. So simple weak arrays approach is not enough to manage distributed objects. Distributed garbage collection is required which is not implemented yet. Of course it is very important feature but for specific applications manual management is usable too. In case of remote debugging everything is cleaned when client disconnects debugger from server.
