Chris,
Thanks and I appreciate your comment. Turns our Java 8_31 is from 2015, so it
was not really reasonable for me to think that would work. Now that I have
upgraded java, I have Fluo uno set up with my local repo so I am able to test
my accumulo changes easily. I am finishing up my second ticket now and should
have it code review today.

The version required to build may change over time, but it is declared
in the pom.xml build configuration, and helpfully checked and enforced
by the maven-enforcer-plugin which will print a message and abort the
build if the requirements aren't met when you try to build. Currently,
1.8 is the minimum required for both the 1.9 branch and the master
branch.
In theory, any 1.8 version should work. We don't specify anything more
specific than 1.8. However, there's nothing we can do about a broken
installation or a buggy version of 1.8 that is later patched to fix a
version that doesn't comply with the 1.8 java specifications. We also
don't do anything to require OpenJDK, Oracle JDK, IBM JDK, or any
other version. If updating your software fixed the issue for you, the
best I can suggest is to keep your build environment up-to-date to
avoid bugs in your build tools.
