Hi, thanks for the replies!
@Lorenz: It would indeed be better to migrate to the latest version.
Unfortunately, this would make the process a bit more
complex...because the functionality I'm trying to add to Fuseki
definitely works with version 3.9.0. Although you are right that the
problem could be solved in a newer version...
@Rob: thanks for the pointer to that bug. At least I can keep my eye
on that one, to see when it gets fixed.
Regards, Barry

Subject: Re: TDBTransactionException: Not in a transaction
This looks like a simpler variation upon JENA-1667 [1] which is a
Known Bug that is not currently resolved in any version of Jena
Although not sure why this worked in past versions of Fuseki, may be a
side effect of other Fuseki refactoring that has happened

Not that I could help here that much, but is there a reason for
migrating from a and old version (2017-12) to a less old version
(2018-09)? I mean, latest release is 3.12.0.
Maybe this might already fix your problem?

Apache Jena Fuseki version 3.6.0.
