Here Geotools discovers a NTv2 transform in the EPSG database and tries to
locate the grid file.
File is not there, so it throws a "NoSuchIdentifier" exception, logs it at
fine level, and jumps to the next available transform.
Not harmful, just informative at DEBUG level.
See "Exception Handling" in IdentifiedObjectSet:
http://docs.geotools.org/stable/javadocs/org/geotools/referencing/factory/IdentifiedObjectSet.html
