Hi @OyvindLGjesdal
We're seeing the same sort of thing.
I think you may be on to something about `conn.update("CLEAR ALL")`.
I can't explain why its always the same test that fails but one server per
test + protected "CLEAR ALL" is working (caveat - its now a quieter time of
day).
I've got some changes that can go to a PR for `main` when cleaned up.
The most annoying failure is `TestFusekiShaclValidation.shacl_no_data_graph`
because it is in `jena-fuseki-main`, whereas the other typical failures are in
`jena-integration-tests` which nothing depends. Running "fail at end" would at
least continue most code checking.
* reinforced the exception handling path to always consume a potential
message and always close the connection,
* Made tests run one server per test (code-change configurable to one per
suite) - this reduces the failure rate to 1 in 10
* Protected `conn.update("CLEAR ALL")` - the error rate on java test
failures is zero
* Move most of the typically failing tests into their own classes for
convenience.
These rates are job failures, runs of both Java17 and Java21, so the
per-build twice as good (it is very rare to have both fail).
The UI issue looks to be an unrelated random failure.
