it's an Oracle feature to convert empty Strings to null
see:  http://www.thunderguy.com/semicolon/2003/04/26/oracle-empty-string-null/ http://www.thunderguy.com/semicolon/2003/04/26/oracle-empty-string-null/
best option is to use a  hibernate UserType for Strings to somehow escape emtpy Strings for jBPM
