RTFEditorKit.write(OututStream,...) throws unexpected InternalError.

Name: aaC67449 Date: 04/17/98



  RTFEditorKit.write(OututStream,...) throws unexpected InternalError, when it must work correctly.

Javadoc says:"
public void write(OutputStream out,
                  Document doc,
                  int pos,
                  int len) throws IOException, BadLocationException

    Write content from a document to the given stream in a format
    appropriate for this kind of content handler.
    Parameters:
        out - The stream to write to
        doc - The source for the write.
        pos - The location in the document to fetch the content.
        len - The amount to write out.
    Throws:
        IOException - on any I/O error
        BadLocationException - if pos represents an invalid location
        within the document.
"
  So InternalError is not right exception any time.
