[keycloak-dev] ConcurrencyTest failures

I've been getting intermittent ConcurrencyTest failures. Tests in error: ConcurrencyTest.testAllConcurrently:57->concurrentTest:49->AbstractConcurrencyTest.run:53->AbstractConcurrencyTest.run:96 » Runtime I'm unable to reliably replicate it but it never happens when running ConcurrencyTest alone (i.e. -Dtest=ConcurrencyTest) but always as part of full testsuite 30 mins into the run. I propose to add: static boolean runIntermittentlyFailingTests() { return "true".equals(System.getProperty("test.intermittent")); } in AbstractKeycloakTest.java and check at the beginning of ConcurrencyTest.java#testAllConcurrently(): if (!runIntermittentlyFailingTests()) { System.out.println("TEST SKIPPED - This test currently suffers from intermittent failures. Use -Dtest.intermittent=true to run it."); return; }
