This bug was initially created as a copy of Bug #1746874

I am copying this bug because: 

We are introducing the curve on RHEL 7, so should do the same on RHEL 8.

This bug was initially created as a copy of Bug #1699068

I am copying this bug because: 

We should keep the number of supported curves in sync between different OpenJDK versions.

Description of problem:
  I have a customer who is using RHEL 7.6 and java-11-openjdk-11.0.1.13-3.el7_6.x86_64(which we ship through rpm).
  While trying to fetch elliptic curve secp256k1 using small java program it is giving the below error instead of returning elliptic curve secp256k1

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[abc@abc]$ java ECKeypair.java 
Exception in thread "main" java.security.InvalidAlgorithmParameterException: Unknown curve name: secp256k1

When I am trying to run the programs mentioned in "Steps to Reproduce" using community version of Open JDK 11.0.2 General-Availability Release.

I am getting below output and program works fine
