I omit first line of race report, sorry.
WARNING: Possible data race during write of size 1 at 0x76a1569c: {{{
...
Where 0x76a1569c is hashCode of object and field.
Also I always add something like this in critical sections:
int hash = System.identityHashCode(this);
long tid = Thread.currentThread().getId();
System.out.println(">>VER>> START WRITE/READ " + tid + " " + hash);
try {
Thread.sleep(10);
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
System.out.println(">>VER>> END WRITE/READ " + tid + " " + hash);
And analise stdout.
This race was verified.
