Could anyone help with this issue? I am running Spring boot 3.3.4 Amazon-corretto-23 aspectjweaver 1.9.22.1. Thanks in advance

[kriegaex]

This simply means that AspectJ 1.9.22.1 does not support class file versions for Java 23+, only up to Java 22.

Please note my recent message to the aspectj-users and aspectj-announce mailing lists regarding my situation as an AspectJ maintainer.

[Dosxx]

Thank you very much! I really appreciate you taking the time to respond.

[kriegaex]

The issue is valid. Why did you close it? I am reopening it.

I encountered the same error while using JDK 23 and AspectJ v.1.9.22.1. Changing the JDK to v.21 fixed the issue. =)
If you prefer to use inbuilt Maven/Gradle Runners in IDE, ensure that you have selected the proper Java version in Settings.

[kriegaex]

Changing the JDK to v.21 fixed the issue.

No, it does not. It is a workaround. What would fix the issue is an AspectJ update supporting Java 23+, hence this open issue until either I find a sponsor and am no longer on hiatus or another committer implements it.
