[jira] [Created] (CASSANDRA-6375) Unit test failures on 1.2 branch
Sylvain Lebresne created CASSANDRA-6375:
-------------------------------------------
Summary: Unit test failures on 1.2 branch

On my box, I get a number of reproducible test failures:

This doesn't end up failing the test and I was actually not able to reproduce when running BootStrapperTest individually, but I don't know if we understand why that can happen during the test (and if it's just an artifact of testing or a real thing).
