Hmm, how well would bukkit plugins like logblock/worldedit (The BIG ones) work in groovy? Will there be the option to make plugins with java?
In other words, will we be able to make large plugins without affecting the servers performance?
The plugin boiler plate needs to be groovy but it just runs to register callbacks and stuff during init. Instead of registering groovy code/closures, you can register regular java classes. It's just a bit more manual. That's mostly what the groovy API is doing, adapting the groovy code blocks to the right java interfaces.
