Steps to reproduce:
$ git clone https://github.com/shipilev/java-concurrency-torture.git
$ cd java-concurrency-torture.git
$ mvn clean install
$ java -jar target/concurrency-torture.jar -t ".*primitiveAtomicity.*ShortAtomicityTest"
Expected result:
Only [0, 0] and [-1, -1] states present.
Actual result:
[0,0], [-1, -1] are present.
One of [0, -1] or [-1, 0] states is present, which means the short value was torn away.
