   * Zip.setWhenempty() has changed its signature.
   
  +* <rmic> is now implemented using a factory. This makes extending
  +  rmic to use a new compiler a lot easier but may break custom
  +  versions of this task that rely on the old implementation.
  +
   Other changes:
   --------------
   
   * Ant now uses JAXP 1.1
  +
  +* rmic now supports Kaffe's version of rmic.
  +
  +* new magic property build.rmic to chose the rmic implementation
