A quick fix for this issue is to convert the bytecount value to double instead of long,

double byteCount = Converter.asDouble(row.getValue("bytecount"));
double bandwidth = (byteCount) * 1000.0 / intervalMilliseconds;

if it is not expected to have bytecount as double then we need to change the query used in RepositoryHistoryManager.maxByteCountReport(..) which make som conditional check on datasize column of repohistory table.
