Official name: Add the ability to write plugins using jruby or groovy
First of all a slight change in the priorities. The top priority now is to enable the support of the bundles that are implemented using scripting language, i.e. Groovy and/or JRuby.
Others nice to have features will be:
1) Enable custom processing for plugin.xml, to be able test the new plug-ins without starting the 2nd eclipse instance.
2) The console, for providing the interactive (re)loading of the plug-in.
I have described to issues in more details in my blog entry.
