Only named ECParameters supported?

Question

I'm having this SSLProtocolException while trying to connect to an OpenSSL server using JDK1.6. The same code is working with JDK 1.5. What does this named ECParameter mean? My OpenSSL server is using NID_sect163r2 curve.
Here is part of my code to generate SSLSocket:
SSLContext sslCtx = SSLContext.getInstance("TLS");
MyTrustManager tm[] = new MyTrustManager[1];
tm[0] = new MyTrustManager();
sslCtx.init(null, tm, null);
SSLSocketFactory sf = sslCtx.getSocketFactory();
SSLSocket socket = (SSLSocket)sf.createSocket(server, port);
And the whole SSL communication message is:
SSLContext class: class javax.net.ssl.SSLContext

Provider: SunJSSE version 1.6

This looks like Sun's Keystore implementation cannot load a ECDSA key if it was created in some particular way:
import java.io.FileInputStream;
import java.security.KeyStore;
public class KeyLoader {
      // For some reason JRE 1.6 cannot recover the key
     public static void main(String args[]) throws Exception {
          FileInputStream fin = new FileInputStream("mykeystore.jks");
          KeyStore ks = KeyStore.getInstance("JKS");
          ks.load(fin, "password".toCharArray());
          ks.getKey("tcsign", "password".toCharArray());
}Exception in thread "main" java.security.UnrecoverableKeyException: Only named ECParameters supported
