Since Java 10, this cannot +be easily concluded from the AspectJ version number anymore, and we are sorry for that. So here is a little overview: + +AspectJ version | Java version | Comments +----------------|--------------|-------- +1.9.8 | 17 | AspectJ compiler requires JDK 11+ during build time. During runtime, AspectJ still only requires Java 8+ for both compile-time and load-time weaving.
