Thejan Wijesinghe commented on TIKA-2293:
-----------------------------------------
I just have some sudden good news to tell. I tried tess4J in a mac even after
excluding Rococoa dependency, I could run the tests. So I contacted the founder
of Tess4J library and asked him about this and this is what he said exactly in
his words,
"You've just uncovered a bug in the software. All these years it has been using
an incorrect type -- the correct one should be that of Leptonica, not Rococoa.
The JNAerator tool we used to generate the Java binding for Leptonica had
erroneously identified and used a wrong data type.
The unneeded dependency, Rococoa, has been removed. It may take a few days to
publish the change to Maven.
That probably has removed the license issue that you experience."
So, I think we are good to go. :) :)
