Hi !

I’ve just tested the new release 2.5 of CloverETL engine.

I found an issue with the DATAINTERSECTION component.

Indeed …

before in the main processing loop of execute method :

```auto
while (runIt && driverRecord != null && slaveRecord != null) {
}

```

in 2.5 :

```auto
do {
}while (runIt && (driverReader.hasData() || slaveReader.hasData()));

```

the problem occurs when the two input (maybe only one) tables are empty there’s a null pointer exception. It was better before cause you didn’t go in the loop if there were not input records.

What do you think ?
