BouncyCastle ALPN broken when running with JDK 11 code compiled with JDK 8

Question

I setup my jdk provider by Security.addProvider(new BouncyCastleFipsProvider()).

Set it in the Grpc client by:

SslContextBuilder sslContextBuilder = SslContextBuilder.forClient()
                    .sslProvider(SslProvider.JDK)
                    .applicationProtocolConfig(new ApplicationProtocolConfig(
                            ApplicationProtocolConfig.Protocol.ALPN, 
                            ApplicationProtocolConfig.SelectorFailureBehavior.NO_ADVERTISE,
                            ApplicationProtocolConfig.SelectedListenerFailureBehavior.ACCEPT,
                            Collections.singletonList("h2")));

When trying to establish the connection, After successful ssl handshake I get:

UNAVAILABLE: Failed ALPN negotiation: Unable to find compatible protocol Channel Pipeline: [SslHandler#0, ProtocolNegotiators$ClientTlsHandler#0, WriteBufferingAndExceptionHandler#0, DefaultChannelPipeline$TailContext#0]

I'm using grpc 1.44 version + bc-fips.jar 1.0.2 version.

Running my app by java 11.0.15 compiled by jdk1.8.0_291.jdk. It looks like BouncyCastleFipsProvider, by its SSLParamertesUtil class, somehow remove the "h2" from the suggested application protocols list. increasing grpc version to 1.46 didn't help.

Any suggestions please? Thanks.
