netty-tcnative-boringssl-static-2.0.46 seems failed to work on s390x

[fjfjfan]

Dear admins,
Thanks a lot for your guide on how to build netty-tcnative, and I've build netty-tcnative 2.0.46
successfully following https://github.com/linux-on-ibm-z/docs/wiki/Building-netty-tcnative, and copy those two jars

netty-tcnative-boringssl-static-2.0.46.Final-linux-s390_64.jar
netty-tcnative-boringssl-static-2.0.46.Final.jar

to work together with grpc-netty-1.42.0.jar and netty-handler-4.1.72.Final.jar following
https://github.com/grpc/grpc-java/blob/master/SECURITY.md#troubleshooting

but I got an error as below now:

2022-01-12 03:31:45 SEVERE dwa.replication.apply.utilities.TerminatingUncaughtExceptionHandler uncaughtException: Thread MainThread threw an exception. Triggering instance restart.
java.lang.IllegalStateException: Could not find TLS ALPN provider; no working netty-tcnative, Conscrypt, or Jetty NPN/ALPN available

Note:

1. on x86, with the default netty-tcnative-boringssl-static-2.0.46.Final.jar/grpc-netty-1.42.0.jar/netty-handler-4.1.72.Final.jar, it works well
2. on s390x, we used netty-tcnative-boringssl-static-2.0.38.Final.jar/netty-tcnative-boringssl-static-2.0.38.Final-linux-s390_64.jar/grpc-netty-1.42.0.jar/netty-handler-4.1.63.Final.jar, the netty-tcnative jars were built following your previous guide, and it works well too.

Any suggestions? Thanks a lot!

rebuild it on RH 8.4, and also copied netty-tcnative-classes-2.0.46.Final.jar, and it works now.
