Re: License review for new itext version



Dear Tom,

Thanks for such a rapid response to my query.

Indeed -- according to upstream itext developers the files in question
were derived from a 2001 version of JAI.

That's useful information, thanks. However, it seems that jai-core
(which contains the file you point to) is dual licensed under the Java
Research License (JRL)  for non-commercial use and under the Java
Distribution License (JDL) for commercial use. As such, I don't
believe this is Free software, and so replacing the files in itext
with the current JAI files isn't an option. I might be wrong though,
and am sure someone will correct me if so.

With that in mind, is there any possibility of Sun relicensing the
files currently in iText so as not to include the nuke clause. For
reference the files are:

com/lowagie/text/pdf/LZWDecoder.java
com/lowagie/text/pdf/codec/TIFFField.java
com/lowagie/text/pdf/codec/TIFFConstants.java
com/lowagie/text/pdf/codec/TIFFLZWDecoder.java
com/lowagie/text/pdf/codec/PngImage.java
com/lowagie/text/pdf/codec/TIFFDirectory.java
com/lowagie/text/pdf/codec/TIFFFaxDecoder.java
com/lowagie/text/pdf/codec/BmpImage.java

OK, so there is a possibility that jai-core is relicensed in the
future - that is encouraging.

Best wishes,
Jonathan.
