It's an Oracle bug.  Looking at releases and forums, they seem to have
iced development, but I don't have specific knowledge if there is
anybody left working on it or not.  Additionally, the licence changes
and format compatibility issues with newer versions have made it a
pain for some packaging/distributing and usage.  Many projects have
moved to lmdb for something somwhat similar, or sqlite.
