When compiling with Java >= 21, the following error is reported

Execution error (ClassNotFoundException) at
jdk.internal.loader.BuiltinClassLoader/loadClass (BuiltinClassLoader.java:641).
java.util.SequencedCollection

This looks caused by the new SequencedCollection interface introduced in Java 21 that's retroffied in the collection API.

Ideally the target compatibility setting should prevent this, but it looks it's ignored.

The following link reports a similar error in Clojure:

The problem the build fails with Java using this error

> BUG! exception in phase 'semantic analysis' in source unit '/home/runner/work/nextflow/nextflow/buildSrc/src/main/groovy/io/nextflow/gradle/tasks/AbstractS3Task.groovy' Unsupported class file major version 66

Interestingly enough this is not nextflow code base the project buildSrc plugin used by Gradle
