yes that works too (slaps head!).

  <target name="addlicense">
    <loadfile srcfile="license-java.txt" property="license"/>
    <replaceregexp flags="s" match="(.*)" replace="${license}\1">
      <fileset dir="src" includes="**/*.java">
        <not>
          <contains text="you may not use this file except in compliance 
with the License"/>
        </not>
      </fileset>
    </replaceregexp>
  </target>


Note that the <contains> file selector only works
on one line at a time, so it cannot use <contains text="${license}"/>

Also, be careful with the contents of the license file,
special characters like \ will cause problems (like \0) with
the regexp replace string.
