Github user ivakegg commented on the issue:
    After an exhaustive search through this code, the only reason I can come up with is an
issue with a member reference in the underlying HeapIterator.  The scenario would be as follows:
    thread 1: calls hasTop() which is invoked on then in memory data source
    thread 2: calls switchSource which sets up the new datasource and calls seek which results
in topIdx being set
    thread1: calls next() which gets a value of null for topIdx
    So if topIdx is marked as volatile then this should not happen.
