Description

Sample Maven pom.xml below:

<project name="&#xFFFFFF;"></project>

0xFFFFFF is not a valid Unicode codepoint. This leads to the following uncaught exception arising from plexus:

Caused by: java.lang.IllegalArgumentException at org.codehaus.plexus.util.xml.pull.MXParser.toChars (MXParser.java:4023) at org.codehaus.plexus.util.xml.pull.MXParser.parseEntityRef (MXParser.java:2727) at org.codehaus.plexus.util.xml.pull.MXParser.parseAttribute (MXParser.java:2522) at org.codehaus.plexus.util.xml.pull.MXParser.parseStartTag (MXParser.java:2218) at org.codehaus.plexus.util.xml.pull.MXParser.parseProlog (MXParser.java:1801) at org.codehaus.plexus.util.xml.pull.MXParser.nextImpl (MXParser.java:1698) at org.codehaus.plexus.util.xml.pull.MXParser.next (MXParser.java:1317) at org.apache.maven.model.io.xpp3.MavenXpp3ReaderEx.read (MavenXpp3ReaderEx.java:4417) at org.apache.maven.model.io.xpp3.MavenXpp3ReaderEx.read (MavenXpp3ReaderEx.java:598) at org.apache.maven.model.io.DefaultModelReader.read (DefaultModelReader.java:105) at org.apache.maven.model.io.DefaultModelReader.read (DefaultModelReader.java:82)

I'm guessing the expected behavior is to throw an XMLPullParserException instead, to signal an unparsable entity.

Found using JQF.
