Summary: Originally, the boolean arguments in Java DB benchmark only takes true and false as valid input. This diff allows boolean arguments to be set using 0 or 1. Test Plan: make rocksdbjava make jdb_bench java/jdb_bench.sh --db=/tmp/path-not-exist --use_existing_db=1 java/jdb_bench.sh --db=/tmp/path-not-exist --use_existing_db=0 java/jdb_bench.sh --db=/tmp/path-not-exist --use_existing_db=1 Reviewers: haobo, dhruba, sdong, ankgup87, rsumbaly, swapnilghike, zzbennett Reviewed By: haobo Subscribers: leveldb Differential Revision: https://reviews.facebook.net/D18687
