Given the file test.adoc (which includes the bibliography macro but does not use any citations):
:bibliography-database: /tmp/ref.bib
:bibliography-style: ieee
# This is a test file
And some example text.
bibliography::[]
When I run asciidoctor -r asciidoctor-bibliography --trace test.adoc, I get the following:

This fails because it assumes the bibliographer's occuring_keys map is empty, since no citations are present in test.adoc.
