> getExternalCMap mehod in CMapParse.class tries to find external CMap, but
> it couldn't find Japan1-65534 and throws exception.
> I know that there is no such a CMap, but it is no problem to open this PDF
> file,
> so I think it is better not to throw exception and use another CMap.
> I modified source code as below temporarily. it works well.

> InputStream is = this.getClass().getResourceAsStream(name);

> is = this.getClass().getResourceAsStream(name);
> if(is == null) {
> throw new IOException("Error: Could not find referenced cmap
> stream " + name);
> }
> }
> return is;

> {code}
> But it is not essential one.
> If possiblećI would like to ask you to modify source code not to throw
> exception if
> it cannot find Cmap.
> I found another Korean pdf file, it includes Adode-Korea1-3 Cmap.
> Please refer to attached file.
> Thanks!
