JamVM is a new Java Virtual Machine which conforms to the JVM specification version 2 (blue book). In comparison to most other VM's (free and commercial) it is extremely small, with a stripped executable on PowerPC of only ~200K, and Intel 180K. However, unlike other small VMs (e.g. KVM) it is designed to support the full specification, and includes support for object finalisation, Soft/Weak/Phantom References, class-unloading, the Java Native Interface (JNI) and the Reflection API.JamVM currently only includes an interpreter (keeps it small). However, the interpreter is highly optimised, and performance is on par with a simple JIT. As most of the code is written in C it is easy to port to new architectures.

Here are some extracts from JavaOne 2008 conference press-releases about Java for IPhone:

"To show Java's prominence in multimedia, rock icon Neil Young made an appearance onstage to promote his video and music catalog offering based on Java and Blu-ray technology. A Sun official also briefly commented on Sun's predicament in trying to put Java on the Apple iPhone, leaving the ball in Apple's court to help make that happen."

"During the post-keynote press conference, Green gave a progress report on Sun's ongoing quest to put Java on the iPhone, something that Apple has not publicly, at least, supported.

Sun, Green said, is well along its way in creating the technology to enable Java to run on the phone, Green said. But he deferred to Apple, which governs which platforms can be distributed with the iPhone. It is Apple's right to decide this, Schwartz added."

JavaOne is one of the most interesting events in IT industry. We are expecting a lot of talks about Java and other technologies. One IPhone+Java - related talk was already mentioned at Java4IPhone.com (link). There are couple more of them.
