I would have to extend some of the 'sealed' classes in Lucene.NET that we use extensively in our products. That would require of me to edit/change th= e library which is constrained by Apache licence. As I understand there are n= o licencing problems if we use unmodified source/binary distribution in our product, but what about modified/changed sources/binaries? Would it be ok, if we just published our modified library, or are there any other requirements/restrictions regarding the usage in our commercial solutions? Can anyone please elaborate on this issue.
