-------------------------------------
Until the C# library participates in the integration tests we will continue to
be plagued by issues like this.

> I have a 30 gig arrow file with 100 batches. the largest batch in the file
> causes get batch to fail - All other batches load fine. in 14.11 the
> individual batch errors.. in 15.1.1 the batch crashes R studio when it is used
> *14.1.1*
> {code:java}
> > rbn <- data_rbfr$get_batch(x)
> Error in ipc__RecordBatchFileReader_ReadRecordBatch(self, i) :
> Invalid: negative malloc size

> gigs.

> fails.
