Description
Thomas Hackel opened BATCH-1820 and commented
This very nice functionality was present in Spring Batch <2.0.
It allows to use the BeanWrapperFieldSetMapper without assigning the column names to the tokenizer.
Please bring back this feature, even its possible to get around with an ugly LineCallbackHandler construction.
Affects: 2.1.8
