I find the extra trailing newlines through below shell command:

for i in `find . -iname "Makefile*" | sed "/./build/d"` ; do tail -n 2 $i | grep -c "^$" | grep -q "^1$" ; if [[ 0 -eq $? ]] ; then echo $i ; fi ; done


There are only two files has been found:

./test/jdk/java/rmi/reliability/benchmark/bench/rmi/Makefile
./test/jdk/java/rmi/reliability/benchmark/bench/Makefile
