When looking around, TestStressIndexing has the same problem (only the time is there 1.0 sec). Attached is a patch also for that. Also this test does not use a volatile variable for the error boolean. Attached is a patch.
There are also other threads that may fail to do anything when the system is under heavy load. Search for "currentTimeMillis" in tests :( ----- Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: u...@thetaphi.de > -----Original Message----- > From: Uwe Schindler [mailto:u...@thetaphi.de] > Sent: Friday, December 18, 2009 8:16 AM > To: java-dev@lucene.apache.org > Subject: RE: Build failed in Hudson: Lucene-trunk #1034 > > Here the patch, Mike, does this look ok? > > When committed we can start a new Hudson run, if you like :-) > > ----- > Uwe Schindler > H.-H.-Meier-Allee 63, D-28213 Bremen > http://www.thetaphi.de > eMail: u...@thetaphi.de > > > -----Original Message----- > > From: Uwe Schindler [mailto:u...@thetaphi.de] > > Sent: Friday, December 18, 2009 7:56 AM > > To: java-dev@lucene.apache.org > > Subject: RE: Build failed in Hudson: Lucene-trunk #1034 > > > > > A new strange test failure: > > > [junit] Testcase: > > > testDuringAddDelete(org.apache.lucene.index.TestIndexWriterReader): > > > FAILED > > > [junit] null > > > [junit] junit.framework.AssertionFailedError: null > > > [junit] at > > > > > > org.apache.lucene.index.TestIndexWriterReader.testDuringAddDelete(TestInde > > > xW > > > riterReader.java:835) > > > [junit] at > > > org.apache.lucene.util.LuceneTestCase.runBare(LuceneTestCase.java:208) > > > [junit] > > > [junit] > > > [junit] Test org.apache.lucene.index.TestIndexWriterReader FAILED > > > > > > > > > (occurred in test-tag!) > > > > > > It's again a multi-threaded test, after joining all threads, the sum > of > > > hits > > > is not >0, so added documents were not seen. > > > > The problem is, the same like with the Benchmark test.
