I was rereading the 2.7 docs about abstract base classes the other day. I
found this line in the usage section of the abc.abstractproperty function:

Hi Irmen,
I have successfully got it to work with both side as python but so far having
trouble with pyrolite.jar which is downloaded from
https://mvnrepository.com/artifact/net.razorvine/pyrolite/4.4
Having simple codes as:
public static void main(String[] args) {

My guess is that is due to an improvement in 3.6 mentioned here:
