@afine Here is the command I've extracted from build logs showing that
junit runs tests on 8 threads:
`[ZooKeeper_branch34_jdk8] $ ant -Dtest.output=yes -Dtest.junit.threads=8
-Dtest.junit.output.format=xml -Djavac.target=1.8 clean test-core-java`
Please let me know if I need to check something else too.---
