Does anyone have an experience with pure AspectJ load time weaving in production systems (mostly interesting Tomcat related activities)? I’m slightly worrying regarding memory footprint and cpu overhead.
I wouldn’t imagine that it’d have a significantly different impact to other AOP-related libraries like cglib, which we use a lot in production systems for AOP proxy generation in Spring. The performance is fine, but there is an increased memory footprint in the permgen pool (due to a large number of synthetic classes being generated), which can be a problem if not managed carefully.
