Shibboleth WWW-Authenticate flakiness: add a test-only config-definition.xml with config-reload=false. Runtime setProperty(...AuthenticationMethod...) overrides were silently discarded whenever the auto-reload listener rebuilt the combined config (restoring clarin-dspace.cfg's [Password, ClarinShib] default), intermittently leaking 'password realm' into the header. Verified: with auto-reload off the override survives; the explicit reloadConfig() reset in @After still works. Hibernate ConcurrentModificationException in @After cleanup: the per-session JDBC ResourceRegistry is not thread-safe, so the CME means two threads touch one Session. Capture a full thread dump on CME (target/cme-dumps/) to identify the colliding thread in CI; keep a resilient retry so an already-passed test isn't failed by this teardown race. (Context.finalize() ruled out: sessions are thread-local.)

Auto-reload is a tested feature here, so it must not be disabled to work around the Shibboleth WWW-Authenticate flakiness. The Shibboleth flakiness (runtime setProperty override discarded when the combined config is rebuilt) needs a reload-safe fix in the auth test instead; tracked separately.

That view is discarded whenever it is rebuilt, and the auto-reload listener rebuilds it as soon as any reloadable cfg file's mtime changes mid-run (e.g. another test writing local.cfg). When that rebuild lands between the override and the request, clarin-dspace.cfg's default [PasswordAuthentication, ClarinShibAuthentication] returns and 'password realm' leaks into the header. The previous clear-then-set helper did not help (it is equivalent to a plain setProperty). Fix: set the sequence via a JVM system property (highest-precedence override layer, re-read on every rebuild) + reloadConfig(), and clear it in @After. This survives auto-reload without disabling it (so AuthorizeConfigIT, which verifies auto-reload, still passes). Verified in the real /api/authn/status endpoint: an explicit reloadConfig() after a setProperty override reproduces the leak, while the system-property approach keeps the header Shibboleth-only across rebuilds. Full AuthenticationRestControllerIT (43 tests) passes, and running it alongside ClarinAuthenticationRestControllerIT / AnonymousAdditionalAuthorizationFilterIT confirms the property does not leak across classes.
