    Description

      Maven 3.6 does not accept the char '>' in XML processing instructions (PI), but '>' is a valid char in PIs. Previous versions of Maven (tested with 3.5) are not affected.

      Example:

      <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>org.apache.test</groupId>
  <artifactId>xmlbugtest</artifactId>
  <version>1.0.0-SNAPSHOT</version>
  <packaging>pom</packaging>
  <?foo bar > bar ?>
</project>

      Maven 3.6 fails to parse the given POM:

      Even if PIs are not evaluated by Maven, they can be used as alternative to XML comments. Example: parquet-1.9.0-cdh6.2.0.pom line 286 is not parsable by Maven 3.6.
