This will allow Gizmo 2 users to generate optimized lambdas and other indy/condy-based optimizations.

See oracle/graal#12453 and quarkusio/gizmo#459 for more information.

Nit: since we're nested in b0, this should be b1, right? :-)

Can't say I understand the change in NativeImageFeatureStep, but LGTM otherwise.

dmlloyd · 2026-04-01T13:42:00Z

I'm going to clean things up and improve the documentation.

dmlloyd · 2026-04-01T13:43:16Z

Hey, it looks like some of the implementation is actually missing. I guess I shouldn't pick up branches after several weeks and just jam them into PRs.

This will allow Gizmo 2 users to generate optimized lambdas and other indy/condy-based optimizations.

dmlloyd · 2026-04-06T21:10:40Z

OK should be reviewable now. Most of the changes are to make build steps register the proper build items.

Aside: the fact that our autoformatter considers this a nice looking code drives me crazy and I have no idea why we accept this. The autoformatter, at least in its current configuration, is terrible.

I agree, it's gotten to the point where I just make super long lines and let the formatter figure it out. I don't even try to make it look good, it's a waste of time.

dmlloyd · 2026-04-07T14:10:37Z

OK so what's happening here is that we are testing in CI with Mandrel-25.0.2.0-Final, but I believe this feature won't become available until 25.1.x is out; @zakkak can you verify that for me? (This is using the new bootstraps registration API in case that wasn't clear)

gsmet · 2026-04-08T20:33:23Z

Making it draft as AFAICS some native tests are failing.

zakkak · 2026-04-16T21:07:10Z

Correct and I don't see it being backported to upstream GraalVM 25.0.x (since it's not a bug) . If it's really important we can try backporting it to Mandrel 25.0.x though, cc @Karm @jerboaa (to share their thoughts).

In the meantime, I guess we could guard the API usage with a GraalVM version check, but I suspect we would also need a different gizmo version which doesn't seem reasonable.

Also FYI there is currently no ETA on when the next GraalVM/Mandrel feature release will happen...

If this is critical enough for Quarkus we should start the backporting process to 25.0 (community repo). I'd expect for certain features needing to land in an 25.0 update. It's not clear if 25.1 (or whatever the next version) will see the light of day any time soon as you say.
