If my understanding is right, I think the following code in MMapRandomAccessVectorValues should return true?

    @Override
    public boolean isValueShared() {
        return false;
    }

Hi fujohnwang,

After reviewing the code I believe you are correct based on the following:

▪	The valueBuffer array (instance field) is reused across all calls to getVector()
▪	Each call overwrites the contents of this shared buffer
▪	ArrayVectorFloat constructor stores a direct reference to the same array
▪	This creates a race condition in multithreaded environments

Thank you for pointing this out, you can submit a PR to correct the issue or I will look into doing so shortly. Once again thanks for your contribution.
