Found another XML issue via Maven, but not sure if it is rooted in plexus-utils.

hang.xml:

<project /><?>

Test:

mvn -f hang.xml
> [INFO] Scanning for projects...   # Gets stuck here forever

My profiler shows me that 100% CPU is being spent in: org.codehaus.plexus.util.xml.XmlReader.read().

I've reported this to Maven in MGN-6374, but I'm not sure which is the right project to report this to.

Versions affected: Maven 3.5.2 and plexus-utils 3.1.0.

This issue was also encountered when fuzzing with JQF.

That's fine, this is the upstream issue, MNG is the downstream one.
