IcedTea-web: Memory leak - java side

[Efrat Lefeber]

Do you know why it was reverted? When will a new patch be released? I am working on a project and it is very urgent for me.

I know some objects are kept around to make subsequent startups faster.
But PluginAppletViewer does not sound like something that belongs on that list.

Adam (Domurad) had proposed a patch to clean memory as much as possible but I think at one point it had to be reverted.

Jiri, Andrew, do you know the status of this?
