It does not work for me either on Mac OSx Sierra. I get the same error as you:

Closing XLogo. Cleaning tmp file
When I looked at the console, you can see that the reason why it does not work is a problem linked to security:
assessment denied for xlogo.jar
com.apple.message.domain: com.apple.security.assessment.outcome2
com.apple.message.signature2: bundle:UNBUNDLED
com.apple.message.signature3: xlogo.jar

com.apple.message.signature: denied:no usable signature

I also tried to run it using Java Web Start, as they explain here :
Java Web Start
Now, you can start XLogo directly from a web page using 'Java Web
Start '(you still need a JRE installed). Just click the following
link:
Start XLogo on line.
And it gives me a security error:
The link that says More information, is this .
On the page say that the latest version of Mac OS tested is: Mac OS X (Tiger Leopard) , which dates from a few years ago.
On the other hand, they offer the source code on this link , a possible solution would be to download it and compile it, and if it gives you a compilation error you could add the missing classes of the javax/media/opengl/ library, because that is what the error message indicates or contact directly with those who have created or maintain the project.
