Java template folder

I'd like to have my module add some templates to the list provided by
the Java module (e.g. "Applet", "Class", etc.). I used to do this by
having templates in my layer file in the folder

  <folder name="Templates">
   <folder name="Classes">

Instead this created another "Classes" dir in the AllTemplates folder;
I tried changing this to imitate the path in java-nature.xml to 

  <folder name="Templates">
   <folder name="SourceFiles">
    <folder name="Classes">

but now they end up in AllTemplates/SourceFiles/Classes. Is it still
possible to add templates to the Java module's directory?
