Justin Bertram commented on ARTEMIS-6054:
-----------------------------------------
Work to upgrade to Netty 4.2.x has already started via ARTEMIS-5734. However,
it's not a particularly straight-forward upgrade due to the transition away
from {{sun.misc.Unsafe}}.
Does Spring have any kind of classloader isolation so that applications can use
their own dependencies instead of those shipped with Spring? If so, I recommend
investigating that as an option to proceed with your upgrade.

> Key: ARTEMIS-6054
> URL: https://issues.apache.org/jira/browse/ARTEMIS-6054
> Project: Artemis
> Issue Type: Bug
> Components: Broker
> Affects Versions: 2.53.0
> Reporter: Shilpi
> Priority: Critical
>
> We are migrating our application from spring 6 to spring 7 with java 25,
> artemis 2.53.0 and netty 4.2.9.
> We are using embedded Artemis broker which is falling on startup after
> upgarde.
> Seems upgrading netty from 4.1.108 to 4.2.9 is causing this issue, as
> NIOSequentialFileFactory is calling the deprecated methods.
> *This is blocking our application upgrade.*
> Artemis broker is falling with below exception:
> {code:java}
