Doc from org.bouncycastle.math.ec.ECPoint.getYCoord.

Returns the y-coordinate. Caution: depending on the curve's coordinate system, this may not be the same value as in an affine coordinate system; use normalize() to get a point where the coordinates have their affine values, or use getAffineYCoord() if you expect the point to already have been normalized.

Returns:ECFieldElement
