Description

It seems that the modelproperty sorting is a bit overzealous. Configure e.g. the exec-maven-plugin thusly:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <configuration>
    <executable>echo</executable>
    <arguments>
      <argument>foo</argument>
      <classpath/>
      <argument>bar</argument>
    </arguments>
  </configuration>
</plugin>

With Maven 2.0.9 I get the expected output

[INFO] [exec:exec]
[INFO] foo /home/espenhw/tmp/target/classes bar

While with 3.0-SNAPSHOT I get

[INFO] [exec:exec]
[INFO] foo bar /home/espenhw/tmp/target/classes

This breaks the common use case of

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <configuration>
    <executable>java</executable>
    <arguments>
      <argument>-cp</argument>
      <classpath/>
      <argument>my.app.MainClass</argument>
    </arguments>
  </configuration>
</plugin>
