From 8748b6c20a0e9f01f6a9b765e26520adb32d95f8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jo=C3=A3o=20Dinis=20Ferreira?= Date: Thu, 30 Apr 2026 22:58:50 +0200 Subject: [PATCH 1/3] fix: pin orbit-aggregation to 4.37.0 to restore test discovery Tests have been silently reporting "Tests run: 0" since #1292 (2026-04-01) bumped orbit-aggregation from 2025-09 to 4.39.0. Tycho-Surefire treats zero discovered tests as success, so CI remained green while test coverage dropped to nothing. Root cause: orbit-aggregation 4.38.0+ ships every JUnit Jupiter, Platform, and Vintage IU at both the 5.x and 6.x version families simultaneously. Tycho's planner pulls in both families, so the OSGi runtime ends up with two Class instances of JUnit Platform types, producing LinkageError / ArrayStoreException during test discovery (different classloaders for the same FQN). orbit-aggregation 4.37.0 (Sept 2025) is the last release that ships JUnit at a single family (5.13.4 / Platform 1.13.4) and matches Eclipse 4.34's PDE JUnit runtime bridge. Pinning to it, removing the now-redundant maven-osgi/release/4.39.0 location, and inlining the JUnit IUs at 5.13.4 / 1.13.4 restores the three JUnit-Platform-bearing classloaders to a single agreed version. Also dropped: the unused releases/2022-12 UML2 location, which was a stealth source of additional JUnit 5.9.1 / 1.9.1 IUs (DDK does not consume any UML2 features). Verified locally on macOS aarch64: 307 tests across 75 classes, 0 failures. Tycho-Surefire's auto-detection selects the junit5vintage provider given Jupiter + vintage-engine on the classpath; no providerHint override is needed. This is step 1 of a staged plan. Subsequent PRs will: step 2 - migrate remaining JUnit 4 source surface to Jupiter step 3 - drop org.junit 4.13.2 and junit-vintage-engine entirely step 4 - upgrade to JUnit 6 + Eclipse 4.39 atomically Credit: Kris Limbo's #1320 / #1321 (Plan A / Plan B) proved the JUnit 5 migration direction; both encountered the same LinkageError during diagnosis that this fix sidesteps via version alignment.

Mockito 5.x treats the second matcher as expecting a second explicit argument, not "varargs may be empty", so verify reports an argument-count mismatch: Wanted: scheduleBuildIfNecessary([], ); Actual: scheduleBuildIfNecessary([]); The test passed under Mockito 4.x where vararg `any()` matched zero or more vararg invocations. This isn't introduced by step 1's 5.21->5.19 patch bump; both are strict. Master has had Mockito 5.x in scope since orbit-aggregation 4.39 (PR #1292), but tests being silent-zero (Tycho-Surefire reporting `Tests run: 0` as success) hid the failure. Step 1 restores test discovery, which surfaces this latent mismatch and makes the test fail deterministically (verified locally: 307 tests, 1 failure on this exact assertion). Drop the second matcher on both verify sites (the never() check and the positive verify); they now match the production single-arg call. The IBuildFlag import is no longer needed. Bundled in PR #1323 so its "restored 307 tests" claim lands green; splitting would ship the orbit-pin PR with a known-failing test.

PR #1292 went undetected for ~30 days for this reason: orbit-aggregation 4.39.0 introduced JUnit 5.x and 6.x simultaneously, breaking JUnit Platform discovery, and CI happily reported pass. Tycho-Surefire writes no TEST-*.xml when discovery yields zero, so a file-existence check on `**/target/surefire-reports/TEST-*.xml` suffices to catch the silent-zero failure mode. The step runs with `if: always()` so it fires even after build failures. Verified empirically: master (orbit-4.39.0, silent-zero) produces 0 TEST-*.xml; the check correctly fails. Working state (orbit-4.37.0, 357 tests) produces 81 TEST-*.xml; check passes.
