Hi Stefy, the stack trace you posted has nothing to do with Apache Lucene. It looks like you are using some commons-lang3 classes here, but no Lucene code at all. So I think your question might be better asked on the commons-math mailing list, unless you have some Lucene code around, too. If this is the case, you should give more information how you use Lucene.
