NPE when column name list contains spaces. E.g. sqoop -import --columns "col1, col2"

sqoop import ... --table JUNK --columns "OWNER, OBJECT_NAME"

The 'space' character between "OWNER," and "OBJECT_NAME" results in a NPE.

ClassWriter.generate() needs to be updated. This method copes with the user supplying column names with the incorrect case - but should also trim each column name supplied by the user.
