broken encapsulation. Rather than accessing the fields of the provider
class here, you could create a method in the provider that contains the logic
ass follows
````
protected void addDatum(StreamsDatum datum) {
try {
lock.readLock().lock();
ComponentUtils.offerUntilSuccess(datum, providerQueue);
} finally {
lock.readLock().unlock();
}
}
