    Description

      From test failure: https://builds.apache.org/job/Lucene-Solr-NightlyTests-trunk/613/

      java.lang.AssertionError: TEST-TestIndexWriterOutOfMemory.testBasics-seed#[C4C9D7B4B9D5D290]: RefCount is 0 pre-decrement for file "_2_2_Lucene410_0.dvd"

      Reproduce with: ant test  -Dtestcase=TestIndexWriterOutOfMemory -Dtests.method=testBasics -Dtests.seed=C4C9D7B4B9D5D290 -Dtests.multiplier=2 -Dtests.nightly=true -Dtests.slow=true -Dtests.linedocsfile=/home/jenkins/lucene-data/enwiki.random.lines.txt -Dtests.locale=mk_MK -Dtests.timezone=America/Vancouver -Dtests.file.encoding=ISO-8859-1
      

      What happened was IW was trying to decRef a set of files, and at
      least one needed to be deleted, then virus checker threw exception,
      and IW later passed the full set of files back to decRef later despite
      that some had already been decRef'd the first time.
