As a build requirement for leveldbjni, we need leveldb-java. There's a Brew project already at https://brewweb.engineering.redhat.com/brew/packageinfo?packageID=45997 which apparently doesn't use the same source as the Fedora package at https://koji.fedoraproject.org/koji/packageinfo?packageID=18420 — we need mvn(org.iq80.leveldb:leveldb-api), given the upstream situation it's possible both packages are appropriate.
I worked around this in the leveldbjni packaging, so it’s no longer needed for OSP12. I do intend to revisit the issue for OSP13 (early in the cycle).
