Please take a review at http://cr.openjdk.java.net/~weijun/8237218/webrev.02/
A test is added that uses a patched ECDSASignature.java that exposes how the signature is verified. BTW, I also updated ECDSASignature.java a little to accept non SunEC keys, so that I can do some interop testing. If you believe this is unnecessary I can revert the change. Thanks, Max
