      public JavaSource getJavaSource(File sourceFile) throws IOException
      Retrieves a JavaSource representation of the specified Java source file.

      Parameters:
      sourceFile - the Java source file to load
      Returns:
      the JavaSource representation of the given file
      Throws:
      IOException - if an I/O error occurs while reading the file
      KotlinNotSupportedException - if the file is determined to be a Kotlin file
