> I've got in my pom:
> {code}
> <properties>
>         <jdbc.schema></jdbc.schema>
> </properties>
> {code}
> And then configured the surefire plugin to set a system property:
> {code}
> <plugin>
>                 <groupId>org.apache.maven.plugins</groupId>
>                 <artifactId>maven-surefire-plugin</artifactId>
>                 <configuration>
>                     <systemProperties>
>                         <dbunit.connection.schema>${jdbc.schema}</dbunit.connection.schema>
>                     </systemProperties>
>                 </configuration>
>             </plugin>
> {code}

> Then it works as expected, no NPE and the property gets set.
> But I need to set the property to an empty string... why on earth does this get turned
into a null?
