["Paul King (Jira)" <ji...@apache.org>]

Paul King commented on GROOVY-11972:
------------------------------------

There are no plans to do any further 2.5 releases. We expect to release Groovy 6 soon at which time Groovy 4.0.x will be the lowest version we expect to provide patch releases for.

>                 Key: GROOVY-11972
>                 URL: https://issues.apache.org/jira/browse/GROOVY-11972
>             Project: Groovy
>          Issue Type: Bug
>            Reporter: Georgii Ustinov
>            Priority: Major
>
> *Steps to reproduce:*
> 1. Consider the following single file project:
> ```groovy
> import groovy.transform.EqualsAndHashCode
> import groovy.transform.ToString
> import groovy.transform.TupleConstructor
> import java.time.LocalDateTime
> import java.time.format.DateTimeFormatter
> import java.util.function.Function
> import java.util.function.Predicate
> import java.util.stream.Collectors
> import java.util.stream.Stream
> @ToString(includeNames = true)
> @EqualsAndHashCode
> @TupleConstructor
> class Order
> { String id BigDecimal amount LocalDateTime createdAt List<String> tags = [] }
> class OrderRepository implements Iterable<Order> {
> String report(Predicate<Order> filter, Function<Order, String> formatter)
> { storage.values().stream() .filter(filter) .map(formatter) .collect(Collectors.joining(System.lineSeparator())) }
> @Override
> Iterator<Order> iterator() \{ storage.values().iterator() }
> String render() {
> def fmt = DateTimeFormatter.ISO_LOCAL_DATE_TIME
> def sb = new StringBuilder()
> sb << "Repository (${size()} orders)\n"
> each { Order o ->
> sb << " • ${o.id}: ${o.amount} @ ${o.createdAt.format(fmt)} ${o.tags}\n"
> }
> sb << describe()
> sb.toString()
> }
> }
> static void main(args) {
> def repo = demo()
> println repo.render()
> def closure = \{ Order o -> "${o.id} -> ${o.amount}" }
> println repo.report(\{ it.amount > 20 } as Predicate, closure as Function)
> Stream.of(1, 2, 3).map \{ it * 2 }.forEach \{ println it }
> }
> ```
> 2. try to compile it with java 25 installed and groovy 2.5.23.
> *Expected behaviour:*
> compilation is succeeded
> *Actual behaviour:*
> ```
> Caught: BUG! exception in phase 'semantic analysis' in source unit '/$USER/RunFolders/IdeaProjects/Groovy25Java25/src/Main.groovy' Unsupported class file major version 69

> I am supporting groovy inside IntelliJ IDEA. Currently, we are migrating our codebase to Java 25. Is it possible to bump the asm version like you did for groovy 3.0.25 and release new artifact?
