Exception thrown while running JMockit tests through ant script

I am trying to run JMcokit tests using ant script. But I am getting exceptions. I have tried to include java agent using 'jvmargs' as mentioned in other posts, also tried to add jmockit jar before junit jar in the classpath, but its of no use. If I add java agent argument in my eclipse, then I am able to run them through eclipse, but not through ant script. The only way I am able to run them through ant script is by adding attach.dll in my java path. But that is not a feasible solution and need a work around.

Ant script:

    <!-- Run the TestSuite -->
            <junit fork="yes" description="Runs the Junit testcase." printsummary="yes"
                haltonfailure="${halt.on.junit.failure}" showoutput="yes">

                 <sysproperty key="java.library.path" path="C:/Program Files/Java/jdk1.6.0_12/jre/bin/attach.dll"/>  

                <jvmarg value="-javaagent:${lib.dir}/jmockit.jar" />

                <jvmarg value=" -Dcom.sun.management.jmxremote"/>


            <!--    <classpath path="${lib.dir}/jmockit-0.999.8.jar" />
                <classpath path="${lib.dir}/junit-4.7.jar" />-->


                <classpath>
                    <pathelement location="${lib.dir}/jmockit-0.999.8.jar" />
                    <pathelement location="${lib.dir}/junit-4.7.jar" />
                    <pathelement location="${lib.dir}/activemq-all-5.5.1.jar" />
                    <pathelement location="${classes.dir}" />
                    <!--<fileset dir="${lib.dir}">
                        <include name="**/*.jar" />
                        <exclude name="**/jmockit-0.999.8.jar, **/junit-4.7.jar" />
                    </fileset>-->
                </classpath>


                <!-- <test name="com.quest.shareplex.hadoopconnector.junits.AllTests" 
                    fork="no" todir="${junit.output.dir}"> <formatter type="xml" /> </test> -->

                <batchtest fork="no" todir="${junit.output.dir}">
                    <formatter type="xml" />
                    <fileset dir="${connector.src}">
                        <include name="**/*Test.java" />
                        <exclude name="**/*HDFSUtilsTest*.java" />
                    </fileset>
                </batchtest>

            </junit>

Please let me know, if there is any other way to work it, or if I am doing something incorrectly. I have tried all the ways that are mentioned on stack overflow: -Tried to change java lib path -Tried to change java class path -Added java agent But nothing is working.

If you are on a Mac, this is happening because the forked JVM doesn't have tools.jar in the classpath. I encountered this today and blogged about it.

It looks like your java is plain jre.

java.library.path java.lang.IllegalStateException: Unable to load Java agent; please add lib/tools.jar from your JDK to the classpath at mockit.internal.startup.JDK6AgentLoader.getVirtualMachineImplementationFromEmbeddedOnes(JDK6AgentLoader.java:82) at mockit.internal.startup.JDK6AgentLoader.loadAgent(JDK6AgentLoader.java:54

Jmockit needs JDK to work.
