Error setting database config property for IDatabaseConnection (HSQLDB)

Question

I\'ve included fully testable code below, which generates the following error when supplied with a dataset xml containing empty fields. A sample dataset.xml

Answer 1

I've stumbled upon the correct answer, at least the one which solves my problem. It related to this line all along databaseTester.onSetup() which could simply be replaced with DatabaseOperation.CLEAN_INSERT.execute(iConn, dataSet);. Feel free comment on why this seemed to have fixed the error.
