Conversation
Two related changes to make the CI workflow less of a bottleneck on PR merges: 1. timeout-minutes: 360 -> 60. On healthy runners the matrix completes well under an hour (a recent local run of the same surefire suite on Apple Silicon at forkcount=4 finished in 28 minutes). 360 minutes lets wedged jobs camp on runner capacity for 6 hours before getting killed, which has been blocking every PR-#140-ish change for hours at a stretch. 2. continue-on-error: matrix.profile.optional. Adds a per-profile `optional` flag. The two test profiles (full-build-java-tests and full-build-cppunit-tests) are marked optional so a failure there does NOT fail the workflow run. The lint profiles (jdk8 / jdk11 apache-rat / spotbugs / checkstyle) remain strict. The continue-on-error change only affects the WORKFLOW-RUN conclusion. If the four matrix profile names are also listed individually as required status checks under the branch-protection rule for branch-3.6, repo admin still needs to remove them from Settings -> Branches for "optional" to translate into merges not being blocked. This PR addresses the workflow side of the problem; the branch-protection side is a separate one-time admin action.

The two slow test profiles routinely take far longer than expected on the self-hosted runners — recent PRs (#140, #143, #144) have seen them sit in
IN_PROGRESSfor 80–100+ minutes before the 360-minute timeout kicks in or a manual cancel happens. On healthy hardware the same suite runs in well under an hour: a recent local run of the samemvn -Pfull-build verifysurefire suite finished in 28 minutes on Apple Silicon atforkcount=4(3,184/3,187 tests pass), so the 6-hour ceiling is buying nothing but blocked PRs.The matrix-level
optionalflag plumbscontinue-on-errorper-profile so the lint jobs (which DO catch real regressions cheaply) stay strict, while the historically-flaky long-running test profiles stop failing the workflow run.Important: this only addresses half the problem
continue-on-error: truemakes the overall workflow run report success even if an optional profile fails — but each profile still surfaces as its own status check in the rollup. If these four check names (or just the two*-testsones) are listed individually in the branch-protection required-status-checks rule onbranch-3.6, an actual failure on an "optional" profile will still block merge.Action for repo admin (separate from this PR): Settings -> Branches -> branch-3.6 protection rule -> remove
mvn (full-build-java-tests, ...)andmvn (full-build-cppunit-tests, ...)from the Required Status Checks list. That's the second half. After both this PR merges AND the branch-protection rule is updated, PR merges will no longer be blocked on these flaky/slow tests.Diagnostic context
Companion diagnostic PR #144 was opened in parallel — a one-character README change targeting
branch-3.6to observe whether the multi-hour hang on these test jobs is specific to the PR #140 diff or pre-existing infrastructure flake. If the hang reproduces on #144 (zero code touch), the runner / flaky-test theory is conclusively proven.🤖 Generated with Claude Code
