> Frustratingly, the seeded failures do not seem to be repeatable. Hmm that is bad ... it means there is a test bug or test infra bug (separate from the scary bug this test is chasing!)? Oh, maybe force `SerialMergeScheduler` to your `RandomIndexWriter`? Since `CMS` (Lucene's default and RIW will sometimes pick that) launches threads and we don't know how to determinize JVM's/OS's thread scheduling, that might explain the non-reproducibility? E.g.: ``` IndexWriterConfig iwc = LuceneTestCase.newIndexWriterConfig(r, new MockAnalyzer(r)), true, r.nextBoolean(); iwc.setMergeScheduler(new SerialMergeScheduler()); RandomIndexWriter riw = new RandomIndexWriter(random(), dir, iwc); ``` or so? -- This is an automated message from the Apache Git Service.
