If you are referring to default functions on interfaces, it's not going to be like multiple inheritance C++ style. Their rationale is to help for backwards compatibility with upgraded interfaces that add methods. Obviously it could be used to intentionally provide default methods from the very beginning, but since I've never designed an interface with that construct in mind I'm personally going to tread lightly with that idea. Thankfully, as far as I know, if two interfaces have a default method with the same signature then the code won't compile versus just "guessing" which one you meant.
If the real crux is lambda expressions have we thought about doing something with either Retrolambda (back porter) or LambdaJ (Google's Apache 2.0 licensed pre-Java 8 lambda library)?
