Description
This failed on 1.8.0u25 G1GC and I was able to reproduce at least once, but not without G1.
svn co -r 1643097 https://svn.eu.apache.org/repos/asf/lucene/dev/trunk cd trunk/lucene/core ant beast -Dtestcase=TestStressDeletes -Dtests.method=test -Dtests.seed=C8F513C39231BFA2 -Dtests.slow=true -Dtests.locale=sk -Dtests.timezone=Singapore -Dtests.asserts=true -Dtests.file.encoding=ISO-8859-1 -Dbeast.iters=1000 -Dargs="-XX:+UseG1GC" -Dtests.dups=8
I am not sure this is possible to debug, but the exception is scary:
