What steps will reproduce the problem?

        <echo>HelloWorld.json processing with jslint</echo>

            <formatter type="plain" destfile="jslint.out"/>
            <fileset   file="HelloWorld.json"/>

What version of the product are you using? On what operating system?

jslint4java-2.0.5.jar

Running apache-ant-1.9.4 under Windows 7 using Java version "1.8.0_31"

Please provide any additional information below.

HelloWorld.json

This same example works OK via command-line invocation:

java -jar lib/jslint4java-2.0.5.jar HelloWorld.json

Attempting to apply jslint4java under Ant using a similar <java> invocation 
fails:

        <java classpath="${jslint.jar}" fork="${fork}">
            <arg value="HelloWorld.json"/>
        </java>
> build.xml:1543: Classname must not be null.

after some sleuthing, found a modified version that works:
        <java classname="com.googlecode.jslint4java.cli.Main" classpath="${jslint.jar}">
            <arg value="HelloWorld.json"/>
        </java>

This form of alternate invocation would be good to add to the jslint4java ant 
page at
http://docs.jslint4java.googlecode.com/git/2.0.5/ant.html

Note that your top-level page still links to the older version of that page:
http://docs.jslint4java.googlecode.com/git/2.0.1/ant.html

p.s. Running jslint --help reveals that a fairly old version of jslint.js is 
being used:
> using jslint version 2013-05-06

p.p.s. looking ahead, Douglas Crockford reports working on a rewritten version 
of jslint:
