Looks like bytebuddy 1.15.4 and above would support 24, according to their README: https://github.com/raphw/byte-buddy

Any updates?

Would also like an update. I see 1.48.0 contains Java 24 fixes on the profiler side: https://github.com/DataDog/dd-trace-java/releases/tag/v1.48.0

But using the latest (1.48.1) version still gives us the above error so the issue remains on the trace side.
