if you are looking for the drop-in replacement for java.util.hashtable, it's in the lib directory, lib/java_util_hashtable.jar. it needs to be in your bootclasspath. example:. a collection of concurrent and highly scalable utilities. these are intended as direct replacements for the java.util.* or java.util.concurrent.* collections but with better performance when many cpus are using the collection concurrently. single-threaded performance may be slightly lower. the direct replacements match the api - but not all behaviors are covered by the api, and so they may not work for your program. in particular, the replacement for java.util.hashtable is not synchronized (that is the point!), although

EDIT: Although yukim's workaround does work, I found that by downgrading to JDK 8u251 vs 8u261, the sigar lib works correctly.

It is not necessary to run cassandra, so you can comment out this line from cassandra-env.ps1 in conf directory: https://github.com/apache/cassandra/blob/cassandra-3.11.7/conf/cassandra-env.ps1#L357
