使用Maven运行testng套件xml时，maven-surefire-plugin中的NullPointerException

Question

I am getting below exception when I am running my testng suite xml with maven without parallel="tests" in suite tag.

When I am running it with parallel="tests" it is working fine. Also, if I am running my testng suite xml from eclipse "run as testng test" without parallel="tests" it is working fine. Please help.

My suite xml-

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name="Filters API" parallel="tests">
    <test name="Filters Test">
        <classes>
            <class name="com.api.testng.modules.filters.FiltersTests"/>
        </classes>
    </test>
</suite>
