[UA-Measurement] Java 8 vs. Java 20

[Mark Datysgeld]

Following up late on this, but: yes, this is consistent with our results 
from the Github software analysis.

If we want a chance to ever improve our results in Java in general, we 
need to influence Java 21-22 to at least gain some ground moving 
forward, as so much software built on that platform relies on the base 
class and it doesn't look like there is a movement towards adopting 
proper libraries.

Best,
