Description

in solr land, HLLUtilTest is an incredibly tiny, simple, test that tests a utility method w/o using any other solr features or doing any logging - as such it extends LuceneTestCase directly, and doesn't use any of the typical solr test framework/plumbing or @SuppressSysoutChecks

on a recent jenkins build, HLLUtilTest failed due to too much sysoutput – all of which seems to have come from the previous test run on that JVM – TestStressReorder – suggesting that somehow the sysout from one test suite can bleed over into the next suite?
