Synchronization on a non-final field

Reports synchronized statement lock expressions that consist of a non-final field reference. Such statements are unlikely to have useful semantics, as different threads may acquire different locks even when operating on the same object.

Example:

private Object o;
public void foo() {
  synchronized (o) // synchronization on a non-final field
  { }
}
