We have a custom PrefixMapper, but from the first look line #188 doesn't look related either: https://github.com/AtomGraph/Web-Client/blob/master/src/main/java/com/atomgraph/client/locator/PrefixMapper.java#L188 Or is it? > > Look at any stacktraces.

It makes the whole thing deterministic. I was looking at the LocationMapper code, but line 188 does not contain anything like that: https://github.com/apache/jena/blob/main/jena-core/src/main/java/org/apache/jena/util/LocationMapper.java#L188 Wrong location manager? Look at any stacktraces. Run 4.4.0. What is the cause and does this need to be addressed? Martynas
