Please take a review at https://cr.openjdk.java.net/~weijun/8214179/webrev.00/
Before this change, `keytool -genkeypair -keyalg EC -groupname brainpoolP256r1` shows Generating -1 bit EC key pair and self-signed certificate... With this change, the message becomes Generating brainpoolP256r1 EC key pair and self-signed certificate... Also, `keytool -list -v` can show Subject Public Key Algorithm: 256-bit EC(brainpoolP256r1) key Thanks Max
