Gradle would like to request a backport of the ASM 9.10.1 bump to Groovy 4, so we can support Java 27 in full: <https://issues.apache.org/jira/browse/GROOVY-12167>

The dependency bump has been merged into GROOVY_4_0_X but we don't claim full Groovy functionality on JDK27 at this point. We'll take a look at further CI coverage when we get time.

From all our testing so far, it is only Groovy Console which doesn't work on JDK26/27 due to an old deprecated JApplet reference. We are discussing what to do about that now.

We'd also be super keen to get some performance testing happening with Groovy 6 once beta-1 comes out (shortly). We have been doing a lot on performance testing. For microbenchmarks, we get 20-25% improvements for "Gradle-like" payloads and 10-20x for some cases:
<https://apache.github.io/groovy/dev/bench/jmh/core-ag/indy/|apache.github.io/groovy/…/indy>
<https://apache.github.io/groovy/dev/bench/jmh/core-hz/indy/|apache.github.io/groovy/…/indy>
It also has `plusAssign` support which should allow some nice improvements for the Groovy DSL and alignment with Kotlin from what I understand.
