Synchronized Method is Overridden by Non-Synchronized method (SMONS)

Description:

SMONS detects if method is declared as synchronized in base class, but is overridden in derived class by non-synchronized method. It is not a bug, but suspicious place, because if base method is declared as synchronized, then it is expected that this method can be called from concurrent threads and access some critical data. Usually the same is true for derived method, so disappearance of synchronized modifier looks suspiciously.
