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

Any updates?

[jeroen-eijsackers-deltafiber]

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.

same here any eta on the updating bytebuddy?

[sarahchen6]

Thanks for your patience! Bytebuddy will be updated to support JDK 24 in the next release. 🙂

[internetstaff]

would sure love to have a release for this. :)

[andron3000]

Yes, everyone is looking forward to this update. Do you have an ETA for the next release?

[sarahchen6]

The 1.49.0 release with the byte-buddy upgrade is planned for Monday, May 5th!

[sarahchen6]

The release has been slightly delayed, but we're working to get it out ASAP. New ETA is tomorrow, but it should be out in the next few days. Thanks for the patience :)

[sarahchen6]

Released!
