Hi David,
Thanks much for the fix! Is there a JIRA entry for this fix? If not, please
go ahead and create one. Then, rename the PR to:
```
DRILL-xxxx: DBC proxy driver: Do not put null value in map
```
That name format is needed by our committers to trace each PR back to the
JIRA entry that describes it.
Thanks!
