> The problem can be reproduced with the following script.
> The ant build script:
> <?xml version="1.0" encoding="UTF-8"?>
> <project name="MavenTest" default="default" xmlns:artifact="antlib:org.apache.maven.artifact.ant">
>     <description>
>             description
>     </description>
>         <taskdef name="mavenTestTask"
>                  classname="maven.test.task.MavenTestTask" />
>        
>     <target name="default">
>     <echo message="Invoking test class that does nothing but echo the classloader"/>
>         <mavenTestTask/>
>    
>     <echo message="Invoking maven artifact:pom task"/>
>                 <artifact:pom id="pom" file="C:/maven-sample/my-app/pom.xml" />
>     <echo message="Invoking test class again that does nothing but echo the classloader"/>
>    
>         <mavenTestTask/>
>    
>     </target>
> </project>
> The simple Ant Task:
> package maven.test.task;
> import org.apache.tools.ant.BuildException;
> import org.apache.tools.ant.Task;
> /**
>  *  Test task demonstrating Maven switching the class loader.
>  */
> public class MavenTestTask extends Task {
>     /* (non-Javadoc)
>      * Intentionally not documented. See parent.
>      */
>     @Override
>     public void execute() throws BuildException {
>         log("Current Class Loader: " + Thread.currentThread().getContextClassLoader());
>     }
>    
> The output when run in Ant:
> Buildfile: C:\Maven\Test\build.xml
> default:
>      [echo] Invoking test class that does nothing but echo the classloader
> [mavenTestTask] Current Class Loader: sun.misc.Launcher$AppClassLoader@e39a3e
>      [echo] Invoking maven artifact:pom task
>      [echo] Invoking test class again that does nothing but echo the classloader
> [mavenTestTask] Current Class Loader: org.codehaus.classworlds.RealmClassLoader@c79809
> BUILD SUCCESSFUL
