> I have a Arq Persistence Ext test method which loads YAML formatted data using @DataSet.
> In the data file I have a mix of tables with data and 'empty' tables. The empty tables are specified to facilitate their cleaning as they contain data created during the test and affect referential FK constraints.
> DBUnit provides for specifying an empty table w/YAML like so where you simply specify the table name and a colon like so:
> MY_EMPTY_TABLE_1:
> MY_EMPTY_TABLE_2:
> When I do that I get the following NPE as it appears Arq persistence dbunit does not do a NULL check when it extracts the columns:
> {code:java}
> Caused by: java.lang.NullPointerException
