Upstream OpenJDK distributed by Oracle does not contain plugin and WebStart implementations, and we add them later via the IcedTea project [1]. That said, I don't think '50% working' is correct for the plugin in Fedora. It works far better than that. Additionally, we follow up on bugs and try to fix whatever we can. However the proprietary nature of many applets makes it quite challenging -- impossible in some cases without decompiling their code, which is something we cannot do. What is the bug# for the Elster system not working?
