Good find - thanks for sharing.

I think some of those topics might be worth further discussion
regarding how/if we use them in the future.

* Optional: I like the idea of using Optional for return types (where
null is/could be returned) - however it might not be worth the
change/effort?
  * As a quick example: JMeterUtils.loadProperties could return
Optional<Properties> (and even log if not found) which would clean up
calling code. Perhaps the getPropertiesAsX methods in TestElement
could also return Optional.

* Default methods on Interfaces: I've been looking at this for the
TestElement Interface
https://github.com/ham1/jmeter/commits/default-methods-TE-interface
I don't know if this is better or worse than the current code - maybe
the interface is a bit too big already (but then again so is the
AbstractClass).

* Parallel streams: should be used with caution, they can be slower
due to the overhead of the parallelism

* These also might be interesting to watch/read:

I was also about to send an email asking about code style - I will
also mention these there.

Thanks again for the link.
