Mail client may be changing changing the char if your copy and pasting, its
- "hyphen" not the unicode en dash –. I would recommend adding it to jvm
options like oleksandr pointed out

Hm, not sure how are you doing it, but it boils down to adding a line
somewhere in the cassandra-env.sh like this one:

JVM_OPTS="$JVM_OPTS -XX:PrintSafepointStatisticsCount=1"

OR, if you're using a newer version (3.0 or newer), the following in the
jvm.options file:

-XX:PrintSafepointStatisticsCount=1
