The problems with Java can't be fixed by adding new things, you can't undo decades of ecosystem development, training, and ideology built on top of the idea that inheritance is really good idea and belongs everywhere.
edit: I will say that as a Java developer I am grateful every day for the improvements to the language. Java is a very impressive language and I have a lot of respect for the people working on it.
