When dumping the AOT Cache file, some classes throw a verification error and are excluded from the cache:

[warning][aot] Preload Warning: Verification failed for io.netty.handler.ssl.OpenSslClientContext
[warning][aot] Skipping io/netty/handler/ssl/OpenSslClientContext: Failed verification

Improve the log message to add the cause of this failure and help the developer understand how to solve it.
