Review comment:
I didn't even remember that, thanks for the link. One of my goals is to
make 1.9.4 work with Java 11 in order to provide a more gradual upgrade path.
People can upgrade to Java 11 while still using Accumulo 1.9, not having to
upgrade to Java 11, Hadoop 3, and Accumulo 2 all at once. I did a round of
testing with Java 11 in the past and just fixed whatever issues I found.
Hopefully I can do that again before 1.9.4 is released.
