Even with the recent update we still get reflective access warnings in the lib.

[JENKINS-52063] Illegal Reflective Access in JBoss Marshalling
I can re-produce this,
2.270, latest pipeline plugins, connect a permanent agent
then a simple pipeline:
node {
sh "echo 'hello-world'"
}

After some further analysis I see there's JDK specific code in jboss marshalling, if you target java 11 when compiling then there warnings do not appear
I patched Jenkins core to compile with 11 (bit hacky due to some dev tooling)
and verified I don't see these warnings any more.
I have not seen this issue since the Pipeline: Support 3.0 release
