For the time being, yes, but I haven't made a final decision yet. For
now I haven't come across anything that I couldn't tackle in a Java 7
compatible way.

Note that Java 7 has been 'end of public updates' since April 2015, and
a number of security patches have been done since then that are only
available to people on Oracle Premier or Extended Support. Staying on
Java 7 (or even earlier) might not be the best course of action if you
don't have access to those updates. Things might be different with
Excelsior Jet.

In my experience, upgrading from Java 7 to Java 8 should be uneventful.
You might run into some corner cases with memory configuration/tuning
with the replacement of the permgen for class metadata with metaspace
(which by default isn't limited), and moving some other data to the
normal heap.
