AspectJ based load time weaving using an LTW aware classloader without Java agent on "java -jar app.jar"

AspectJ based load time weaving (LTW) can be set up with Spring Boot, however when running as a dead simple "java -jar app.jar" the classes are not woven until Java agent is specified. (AspectJ + LTW + self contained JAR) is a potentially cool combination for many Spring Boot powered projects that need to leverage AOP without needing to play any additional tricks (or worrying about not forgetting to).

This feature request is about adding an AspectJ LTW bootstrapping code straight into the Spring Boot launcher where a specific class-loader is initialised. Then, the client projects that would like to stick with the simplest "java -jar app.jar" startup way would be able to leverage power of AspectJ LTW weaving feature out of the box.

Start by tracing the Spring Boot launcher and the class-loader initialization used by a self-contained java -jar app.jar launch. Determine how AspectJ LTW bootstrapping could work without a Java agent, then define and validate the expected behavior for client projects; the issue names no specific files or tests.
