Description

The following will generate a null pointer exception when it is in the project POM. (or potentially any pom, I don't know)
...

<profiles>

    <id>localdev</id>
    <activation>
      <os>
        <name>Windows XP</name>
      </os>

      </property>
    </activation>
    <build>
...
