Description

Wrong casting of long value to int leads to incorrect results:

    /** {@inheritDoc} */
    @Override public int pages() {
        if (!inited)
            return 0;
        
        // allocated.get() returns long value. We should cast it to int after division.
        return (int)((allocated.get() - headerSize()) / pageSize);
    }
