sha256 checksums are not correct

For counting sha256 checksums and comparing them with SHA256 checksums inside zip, I am using this simple script: #first go to directory containing the natives zips and then run: for i in `ls jboss-ep-native-5.2.0-ER2-*`; do echo ------ FILE $i; unzip -l $i | grep SHA256SUM; temp_dir="xxx-$i" mkdir $temp_dir; unzip -q $i -d $temp_dir/; cd $temp_dir/; find -L jboss-ep-5.2 -type f -print0 | xargs -0 sha256sum > directory.SHA256SUM; cat jboss-ep-5.2/native/SHA256SUM |sort > fromZIP; cat directory.SHA256SUM | grep -e \\.so -e la$ -e dll$ -e exe$ | sort > generated; diff generated fromZIP; cd ..; rm -rf $temp_dir; done
