Robert - we can go to two approaches here with logging both require you
to define a log4j category for EncryptionUtils

First approach - as I suggested, move to FATAL - you will not see these
errors.
Second approach - move to DEBUG. I looked at the code, and saw that if
you define a category for EncryptionUtils  with DEBUG level you will
also get a print of stacktrace, this may assist in understanding the
problem you're facing.
