Maven 2.1.0 not passing on system properties to Java virtual machine

We use the command line to pass on system properties to the Java virtual machine when running our Hudson builds on a Linux box. It used to work quite well in 2.0.9 by since we upgraded to 2.1.0 it has stopped working altogether. The system properties just never make it to the Java virtual machine.

I have created a small test project and indeed it does not work at all.

This should work just fine with Maven 2.0.9:

mvn2.0.9 -Dsystem.test.property=test test

But this will fail:

mvn2.1 -Dsystem.test.property=test test

The Java code simply does this 

assertTrue( System.getProperty("system.test.property") != null);
maven-2 jvm maven-plugin surefire system-properties

I've experienced this with the Surefire plug-in. The Surefire plug-in is run under a different JVM instance that is launched by Maven. The command line params are configurable under the surefile-plugin configuration in your pom.xml. Here is a sample of our configuration.

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.4.3</version>
            <!--
                    By default, the Surefire Plugin will automatically include all test classes with the following wildcard patterns:
                    "**/Test*.java" - includes all of its subdirectory and all java filenames that start with "Test". "**/*Test.java" -
                    includes all of its subdirectory and all java filenames that end with "Test". "**/*TestCase.java" - includes all of
                    its subdirectory and all java filenames that end with "TestCase".
                -->
            <configuration>
                <includes>
                    <include>**/*Test.java</include>
                </includes>
                <systemProperties>
                    <property>
                        <name>app.env</name>
                        <value>dev</value>
                    </property>
                     <property>
                        <name>oracle.net.tns_admin</name>
                        <value>${oracle.net.tns_admin}</value>
                    </property>
                </systemProperties>
            </configuration>
        </plugin>
