Description
SE 15 brings in https://openjdk.java.net/jeps/371, which introduces the notion of 'hidden' classes. It seems that for such classes, calling Unsafe.objectFieldOffset will (deliberately) fail.
This is problematic for JBoss Marshalling as SerializableField relies on making that call. So if any class that is hidden is marshalled, that will likely fail.
This is resulting in a couple failures in my work with getting WildFly Preview to run much of its TS with SE 15.
See https://ci.wildfly.org/viewLog.html?buildId=254549&tab=buildResultsDiv&buildTypeId=WF_Ee9LinuxJdk15
For example StatefulWithXPCFailoverTestCase fails. The interesting part of the server log is:

I believe the issue here is the classes behind some lambdas are being generated as hidden classes with SE 15. Specifically, I think this from org.hibernate.internal.AbstractSharedSessionContract is the issue:
private StatementInspector interpret(StatementInspector statementInspector) { if ( statementInspector == null ) { // If there is no StatementInspector specified, map to the call // to the (deprecated) Interceptor #onPrepareStatement method return (StatementInspector) interceptor::onPrepareStatement; } return statementInspector;
I believe that because the stack trace includes this line:
at org.hibernate@5.3.20.Final//org.hibernate.internal.AbstractSharedSessionContract.writeObject(AbstractSharedSessionContract.java:1122)
which is this:
oos.writeObject( jdbcSessionContext.getStatementInspector() );
The other StatementInspector impls are normal anonymous inner classes so I don't expect they'd be hidden classes.
