> This was triggered when running our sitereporting test ( [https://github.com/repaint-io/maven-tiles/tree/master/src/it/sitereporting-tiletest] ) and doesn't trigger an NPE using Apache Maven 3.5.3, but does with the current SNAPSHOT of 3.6.2.
> The problem lies when Maven is building the model from [https://github.com/repaint-io/maven-tiles/blob/master/src/it/sitereporting-tiletest/tile-tile/tile.xml#L35] and can be fixed by applying the patch found at [https://www.dropbox.com/s/9gficrmlgxl2jd0/0001-Fix-NPE-thrown-from-DefaultReportingConverter.patch?dl=0] (for some reason I could not attach the patch to the ticket).
