Apache Ant & Java WSDL Import - fatal error

Question

Our application is build on Java 7 and the other application is build on Java 8. I have imported the wsdl url certificate using keytool & using Java 8 I'm able to generate the Jar. But when I use Java 7 it gives me [ERROR] Received fatal alert: protocol_version

I'm using ant to generate the jar.

<target name="abcService">
        <delete dir="${build.dir}/jar/" />
        <mkdir dir="${build.dir}/abcService" />
        <echo message="building client classes....."/>
        <wsimport 
            debug="true" extension="true"  package="com.abc.abcService"             
            wsdl="https://abc-test1.corp.intranet/ABC/services/AbcServiceImplPort?wsdl" 
            destdir="${build.dir}/abcService">                  
            <xjcarg value="-XautoNameResolution"/>
        </wsimport>
        <echo message="Jarring the classes generated using wsimport..."/>
        <jar destfile="${build.dir}/jar/abcService.jar">
             <fileset dir="${build.dir}/abcService" />
        </jar>           
   </target>
