> Use jctools-core-jdk11 Unsafe-free varhandle replacements
> ---------------------------------------------------------

> Key: ARTEMIS-5948
> URL: https://issues.apache.org/jira/browse/ARTEMIS-5948
> Project: Artemis
> Issue Type: Improvement
> Reporter: Christian Ortlepp
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Artemis currently uses some queues from jctools-core which rely on
> sun.misc.Unsafe internally. These methods are deprecated in JDK24+, issue a
> warning at runtime and will be removed in future versions of the JDK. Thus it
> makes sense to switch to an implementation which does not rely on those
> methods.
> In their latest
> [release|https://github.com/JCTools/JCTools/releases/tag/v4.0.6] JCTools have
> started to publish a new artifact, jctools-core-jdk11, which contains
> alternative Varhandle based implementations which do not use Unsafe. As far
> as I understand them they are designed to be a drop-in replacement to the
> existing Unsafe implementations.
> It would be great if we could either switch to the new implementations
> entirely or provide it as an option somehow for the people that would like to
> avoid Unsafe. I will link a PR shortly where I switched over to the new
> implementation, but I am open to feedback if for example we can only do this
> change opt-in.
