After libsunec is removed, the EC-related cipher suites should be excluded from the supported cipher suite list, and the ECDSA schemes should be excluded from extensions signature_algorithms and signature_algorithms_cert.
Comments
After the push of JDK-8237219, the native SunEC implementation has been disabled by default.
Even if libsunec is removed, the EC-related cipher suites and ECDSA schemes are still there.
When libsunec is removed someday, we could just check if the existing JSSE tests, which contain a lot of EC-related tests, pass.
So, it may be unnecessary to develop a separated test for this point.

JDK-8237219 introduced a new system property jdk.sunec.disableNative for disabling the native SunEC.
