Description

I upgraded Jena from 2.11.0 to 3.0.1 and OntModel imports stopped
working when getOntology() is called.

I traced the problem to

AdapterFileManager.readModelWorker(Model model, String filenameOrURI, String baseURI, String syntax)

where

model.read(in, baseURI, syntax)

was at some point replaced with

RDFDataMgr.read(model, mappedURI, baseURI, lang)

and therefore OntModelImpl.read() doesn't get called, and
OntModelImpl.loadImports() doesn't get called.
The workaround is to call OntModel.loadImports() explicitly.

Respective stacktraces provided below.
