This should probably still retain the lazy buffer array creation:
Suggestion:

size;
        if (getClass() == BufferedInputStream.class) {
            // lazily create buffer when not subclassed
            buf = EMPTY;
        } else {
            // eagerly create buffer when subclassed
            buf = new byte[size];
        }
