Review Comment:
I think it would be useful to add to the description something like
"if set to 'false' it means full compliance with RFC-4180".
This is because a new user who hasn't used this before selects RFC-4180 as
the CSV format, they would probably only want to know what value of this
property guarantees that.

Review Comment:
Just like in the case of the constructor of CSVRecordReader, I recommend
overloading this method with a variant that does not contain the
`trimDoubleQuote` parameter, and it should call this method with
`trimDoubleQuote=true`.

Review Comment:
I recommend reintroducing the declaration of the original constructor, and
the implementation should just call this constructor with
`trimDoubleQuote=true`. This way everywhere where you called this constructor
with `trimDoubleQuote=true`, you could revert to calling the original
constructor.

Review Comment:
Same as in the case of CSVRecordReader: I recommend reintroducing the
declaration of the original constructor, and the implementation should just
call this constructor with trimDoubleQuote=true. This way everywhere where you
called this constructor with trimDoubleQuote=true, you could revert to calling

I believe this is an accidental auto-import. Could you please remove it?
