Mamta A. Satoor commented on DERBY-5531:
----------------------------------------

I have been debugging this issue and found that, for some reason, for a non-null value, we have a NormalizeResultSet which does the conversion for char to territory based char equivalent at execution time. But, for null value, we do not have NormalizeResultSet and hence no such conversion of data type happens. The conversion probably is not necessary since we are dealing with nulls. I am debugging further to see where the decision is happening about the requirement of NormalizeResultSet.
