Thanks for adopting the new AspectJ version so quickly. I am looking forward to your feedback. Not knowing what the minimum Java version is in your build system, please note the following caveat:

• The Eclipse Java Compiler (ECJ) 3.2.7 supporting Java 17 now needs JDK 11+ as a build environment, because Eclipse migrated the code base to Java 11. Because the AspectJ Compiler (AJC) contained in aspectjtools is an ECJ fork, using a Java-17-enabled AJC version (1.9.8.RC1 and higher) means that you need to run your build on JDK 11+. You can still compile to goals as low as Java 1.3, don't worry. It is only about the build environment. I am not sure if you even use AJC or depend on the AspectJ Tools library anywhere, please check.

• As for LTW, I just verified that for now, the class files contained in the smaller aspectjweaver agent library still do not contain any Java 11 class files, i.e. LTW should still work on JDK 8 systems.

You're welcome. We're glad to help integration test with the RC before the GA release.

Our build is working fine with the changes in fa3a2dc.

Not knowing what the minimum Java version is in your build system, please note the following caveat:

For Spring Framework 6.0 (main), Java 17 is the baseline for the build and any applications using Spring 6.0.

I'm about to close this issue with an upgrade to AspectJ 1.9.8 RC3 (for 6.0 M1). We can track the AspectJ 1.9.8 GA upgrade in #27416 then.
