Yeah, I had this problem the other day and these guys helped me to resolve it...

This is the solution that they came up with.  I was compiling all my java source with java 1.3 but wanted to build my javadocs using
java 1.4....

<target name="buildJavadoc" depends="initCommon" >

        <!-- Build the javadoc in a seperate ant process so that we can use version 1.4 of the javadoc utility -->
        <exec executable="ant">
            <arg line="-buildfile ${ant.file} javadocCreate"/>
            <env key="JAVA_HOME" value="${java_home1.4}"/>
        </exec>

        <echo message="Reverting back to Java ${ant.java.version} for remainder of build..."/>

</target>

<target name="javadocCreate" depends="retrieveFileNamesForJavadoc" >

        <javadoc sourcepath="${pcp_source_dir}:${parlay_src}:${parlay_rel4_src}"
            classpath="${sdk_jar_file}:${corba_classpath_stuff}"
            packageList="${working_directory}/tmpJavadocInput2"
            ....
            ....
