Failure to scan a project with empty properties in the pom.xml

[fabapp2]

Thanks @virgium03 for raising this issue!

Version: 0.9.1.

If any of the pom.xml files in a project contain empty properties elements, the tool fails. The fix is to remove the empty properties element from the incriminated pom.xml file.

Examples which generate a failure:

<properties> </properties>

or

<properties>
 
</properties>

The stacktrace is as follows:
