Two -XX:SurvivorRatio arguments in cassandra.in.sh

[Tim Underwood]

It looks like CASSANDRA-504 commit added a second -XX:SurvivorRatio argument
to cassandra.in.sh. Was this intentional?

JVM_OPTS=" \
        -ea \
        -Xdebug \
        -Xrunjdwp:transport=dt_socket,server=y,address=8888,suspend=n \
        -Xms128M \
        -Xmx1G \
        -XX:SurvivorRatio=8 \
        -XX:TargetSurvivorRatio=90 \
        -XX:+AggressiveOpts \
        -XX:+UseParNewGC \
        -XX:+UseConcMarkSweepGC \
        -XX:+CMSParallelRemarkEnabled \
        -XX:+HeapDumpOnOutOfMemoryError \
        -XX:SurvivorRatio=128 \
        -XX:MaxTenuringThreshold=0 \
        -Dcom.sun.management.jmxremote.port=8080 \
        -Dcom.sun.management.jmxremote.ssl=false \
        -Dcom.sun.management.jmxremote.authenticate=false"
