             Summary: Exception thrown in Maximum Bandwidth Report 
                 Key: CONNECTORS-1195
                 URL: https://issues.apache.org/jira/browse/CONNECTORS-1195
             Project: ManifoldCF
          Issue Type: Bug

    Affects Versions: ManifoldCF 2.0.2, ManifoldCF 1.8.2
            Reporter: Kishore Kumar


This exception occurs when the _bytecount_ value returned is double instead of the expected long value.

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

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

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.
