Set up Netty-with TLS handsake with ECC and RSA client certificate auth

Question

I am working on a remote server that uses Netty to perform client authentication with a TLS handshake through the Netty SSLHandler library. This S/O question gives a bit: Set up Netty with 2-way SSL Handsake (client and server certificate)

Now, the question I have about this system is that the Server requires a TrustManager to initialize a SSLContext. From what I observe this uses the SunJSSE provider. Now after setting up this implementation, I got it working with RSA client certs. Now, I am having trouble using ECC client certs as SunJSSE cannot recognize them (I think Java SE 7 include SunEC as a provider. But SunEC is a SunJCE implementation and not a SunJSSE one and thus cannot be used as a provider for TrustManager). So, how do I proceed. I heard Bouncy Castle can recognize these certs, but I still cannot instantiate a TrustManager with BC as the provider.

Edit: Also if there is no way to use TrustManagers, should I do the entire handshake only use BouncyCastle's API's and not netty's libraries? That seems off though. This is my other S/O question that shows the stack trace: Client ECC SSL Certificate contains "unknown named curve"

Sorry that you didn't receive an answer. Yes, generally you need to add ECC functionality before you can update the protocols that use it. I assume this works for newer versions of Java. Is this question still applicable to you? – Beauvoir
