New stuff in Java asynchronous world

There's a lot going on related to asynchronous stuff in Java.

• Java 1.5 and its concurrent collection

• IBM and its Asynchronous IO for Java

• ActiveMQ and its RESTful API

I expect to see a new breed of message bus which leverages all this stuff and others (e.g. NIO) to provide the core infrastructure to build <buzzword>SOA</buzzword> applications.
