             Summary: CsvDataContext.executeCountQuery breaks if Resource.getSize() returns -1
                 Key: METAMODEL-30
                 URL: https://issues.apache.org/jira/browse/METAMODEL-30
             Project: Metamodel
          Issue Type: Bug
            Reporter: Kasper Sørensen
            Assignee: Kasper Sørensen


On line 282 of CsvDataContext we check the size of the CSV resource (typically file) like this:

final long length = _resource.getSize();

But the Resource interface says that a resource may return -1 to this method, if the size is not determinable.

In that case our code breaks since there will eventually be a negative sample data array created from this value.

Rather we should check for the exceptional -1 value and handle the sample array size accordingly.
