It's there !
I am very pleased to announce the prototype version of JRockit that includes our AOP API is available. It will drive you far far away from current bytecode instrumentation techniques to a world of plain Java API, complete runtime control for hot deployment and undeployment, agnostic from the programming model you like for your aspects.
If you are involved in the AOP field, bytecode instrumentation field, APM field, and did not heard from us recently, please drop me an email and I 'll consider your participation in evaluating this technology to help us drive it to reality.
You can read the official announcement and some background information in our BEA dev2dev dedicated forum.
