Bisecting leads to the commit that added the test; it was added (failing)
for #24282, and the failure was later fixed.
The failure on Oracle is unrelated to the problem reported on the ticket,
but since the solution (b29f3b51204d53c1c8745966476543d068c173a2) involved
a rewrite of model reloading, it may be related.
