[Native Image] r.n.http.client.HttpClientConnect : The connection observed an error com.oracle.svm.core.jdk.UnsupportedFeatureError: Support for Arena.ofShared is not active: enable with -H:+SharedArenaSupport #12318
Description
Describe the Issue
I am using an app which uses spring reactor to make a http request in a rather high frequency to a backend.
Things are working very well, until the bump to GraalVM JDK25
We did no code change, just the graalvm bump from 24 to 25.
As of now, when using graalvm25, I am able to reproduce 100% this error:
