It is different, and takes significantly less time. In incremental mode the
compiler hangs on to the unchanged class' bytecodes so that it can re-weave
them quickly.

Yup. But another thing worth considering here is improved dependency
analysis of aspects. For example, it will be straightforward to improve the
incremental behavior to restrict recompilation to the aspect if only the
body of advice changes. More will need rebuilding when you change a
pointcut designator, but that should be inline with expectations. So in the
long term I'm confident that the tools will enable a uniform way of working
with and reasoning about classes and aspects. That's not to say that the
user doesn't need more control over rebuilding before these improvements are
implemented.

Due to the wide range of Java projects and practices we need user feedback
to get these sorts of options and defaults right. I expect to post the
document sometime in the next few weeks, and look forward to your comments.
