Description

CASSANDRA-1181 added -XX:ThreadPriorityPolicy=42 jvm flag to support setting native thread priority without root (based on the workaround described on http://tech.stolsvik.com/2010/01/linux-java-thread-priorities-workaround.html).

On Java9 this wokaround will not longer be possible due to JEP 245 so this flag should be removed.
