- add more debugging output to find source of nullpointer exception

- workaround, because Fixity.FixityAlgorithm.MD5.toString() returns "MD5" as
uppercase, but fixity.getAlgorithm() returns "md5" as lowercase. This is a bug
in Rosetta SDK. As a workaround, we call "toLowerCase()" methods before
comparison.
