Hans Lund commented on LUCENE-5461:
-----------------------------------

Yes exactly:

java.lang.AssertionError: waited too long for generation 10001
        at org.junit.Assert.fail(Assert.java:88)
        at org.junit.Assert.assertTrue(Assert.java:41)
        at 
org.apache.lucene.search.TestLucene5461.testCRTReopen(TestLucene5461.java:94)


I've noticed when extracting the test that changing directory implementation 
influenced how often the test failed: - using a RAMDirectory failed to trigger 
the test. I've not tried with FSDirectory.

> If setting the tagetMinStaleSec to 0, sometimes a call to waitForGeneration 
> will block for targetMaxStaleSec instead of immediately call 
> maybeRefreshBlocking on the manager.
> In effect to targetMaxStaleSec cannot be set higher than acceptable blocking 
> resolving of a specified generation.
