Yes.

The Java standard API sports the 'java.util.concurrent' package (and related)
<http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/package-frame.html>

Multi-threading is built into the very language. Even normal "synchronized"
blocks perform well under many typical circumstances.

I don't know what "Fill-Empty bit blocking" is, but if you give up looking for
specific idioms and specify the strategic goals, you'll find what you need in
Java.

As to which combination of the API calls will be "best" for you, that depends
entirely on your needs. Different parts are "best" for different use cases.

So the question is, something that scales *what* up efficiently would be nice
for you?
