                                           throws java.io.IOException

  Define a class given its bytes

  Overrides:
    `defineClassFromData` in class `AntClassLoader`
  Parameters:
    `container` - the container from which the class data has been read may be a directory or a jar/zip file.
    `classData` - the bytecode data for the class
    `className` - the name of the class
  Returns:
    the Class instance created from the given data
  Throws:
    `java.io.IOException` - if the class data cannot be read.
