Byteman on JDK10

[sannegrinovero]

Hello,

our project has been using Byteman 4.0.0 recently and all is working well, even on Java 9.

But now we're building on JDK 10 and the rules are no longer applied:

[WARNING] Bundled version of ASM cannot parse bytecode of java.lang.Object class; marking runtime as not suppported.

Does anyone know if I can just override the ASM dependency of Byteman?

I was going to give it a try but couldn't find a new ASM release in Maven. I see an ASM 6.1-beta was tagged:

- https://gitlab.ow2.org/asm/asm/commit/d473d99c9b2b27abe207b82d19f6c7e0d4a05085

Thanks, Sanne

I don't believe that's going to work. Byteman includes its own shaded version of the ASM code in the agent jar. I will need to push a new version of Byteman to use a later asm release.

I think this is going to be an continuing issue with consumers of ASM because class file magic numbers are going to continue rising with each new JVM release. Hmm, what a pain.

Thanks Andrew, I was looking for a 6.1 release of ASM (which isn't ready) but it seems just 6.0 should work as well. I'll do some tests locally and let you know. Regards, Sanne

Hi Sanne,

Byteman needs to integrate asm-6.1beta2 in order to be able to read classfiles with jdk10 versions.

I have a patched version in the works: see BYTEMAN-355

Thanks!

Looking forward for a release; I've also sent a pull request to make the build (and release!) process a bit more convenient.

I've built the latest Byteman release locally, and happy to confirm it works fine on Hibernate Search (including on JDK10). Looking forward for the next release!

Excellent. I have also pulled the docs pom patch.

I will try to get the 4.01 release out today.
