Hi Scott,

Interesting to hear about the possibility of a Batch MR!

So with EE 8 requiring Java 8 (hopefully a correct assumption), and with

That assumption should be correct. See the platform JSR:

Specifically both JSR 372 and 375 have already started taking advantage of
Java 8 in the implementation of their respective RIs.

The Servlet 4.0 spec has done exactly what you mentioned, adding new
methods to interfaces and using a Java 8 default implementation of those
for compatibility.

Kind regards,
Arjan Tijms
