The alternative:

<path id="my-src-dirs">
  <dirset dir="common-parent-of-src-and-test">
    <include name="path-leading-to-src" />
    <include name="path-leading-to-test" />
  </dirset>
</path>

<javac ...>
  ...
  <src refid="my-src-dirs" />
</javac>

This may look more complicated, but ...

If either of both directories is not there, it will not be included in
the dirset and thus not show up in the path (requires Ant 1.5).
