I'm not sure if I missed something.
It seems to me JCStress does not catch an error situation.
The issue is, when I run the test(please check run.sh attached), in console log I can see below error message outputed:
"
Interruptor thread did not terminate:
java.lang.Exception: Stack trace
"
it means there is fail, so I expect that Occurrences for state "1" is not zero.
but, the Occurrences for state "1" is always zero, means it never failed.

Please check attachment for details, you might need to modify run.sh to
 1. setup your own jdk 9 environment
 2. Setup maven path
