Hi Alexander, Thanks for the link/pointer. I read through it, but am still unclear how/where this becomes useful. It is obvious how it can be used in a standard console java application with a single "main" entry point. This would also apply to any self-contained Spring Boot applications (or their equivalences). But can something like this be used in any web container? Be it a tomcat, jetty, wildfly, etc. ? I don't know of a single entry point, equivalent to a "main" in a console application.
>From what I understand from the release notes, any classes loaded prior to the LTW agent being attached won't be woven. So in the case of a JEE app (ie: EJBs, etc), the container scans and loads beans in the Dependency tree long before the application "starts". So one would need to hook into the classloading mechanism itself, or provide a custom classloader? Do you know if there is a mechanism to do this reliably? I would obviously want the Agent loaded as the first class in my EAR.
