Sun recently announced the availability of a second edition of its Java Real-Time System (Java RTS) version 2.2 Early Access. In a previous blog post, many of the important new features of this release were highlighted. But I felt compelled to jot down a few additional words, not only because there's a newer version of the software to evaluate, but because there's one interesting component that deserves a little more exposure.
I spent some time today speaking with my compadre, Eric Bruno, author of Real-Time Java Programming: With Java RTS. He clued me in on the fact that our engineers have performed the daunting task of backporting the JDK 7 client compiler onto Java RTS 2.2. The engineering team is particularly proud of this feat, and ought to be. It not only enhances Java RTS performance, it also enables them to better stay in lock step with the latest client hotspot VM developments, something the latest Java SE 6 releases may not entirely do. For some insight into the engineering trade-offs associated creating this latest version of Java RTS, check out Roland Westerlin's entry.
