Error with com.landawn.abacus.logging.JDKLogger log about abacusutil HOT 7 CLOSED

It's a bug. The root cause is the JSONParserImpl class isn't initialized successfully due to the cycling dependence between it and class N. It's fixed in version 1.0.5. please download the new version and let me know if you have further questions.

Thank you for reporting the issue and I hope you will enjoy using the library.

Hi there
Thank you for the respond and fix, but found the new error is thrown as below. At least it is not the same so i can see i will be able to use your software soon :-)

Could you please show me your test code and couple of lines of the sample CSV file? so i can find out the root cause?

Thanks! i didn't find the attached CSV file you used for test for some reason. Can you please check it for me or upload it again if it's missed?

I still didn't see the attached CSV file you used for test. but anyway, if you want to continue to give it a try. Here are my suggestions:
If the column values in the CSV files are quoted with " or ' except type: number or boolean. For example 001.csv:

first_name, last_name, number
"tom", "cruise", 1
"tom", "hanks", 2

The simplest way to load it to DataSet is:

File csv001 = new File("./001.csv");
DataSet ds001 = CSVUtil.loadCSV(csv001);
ds001.println();

If the column values in the CSV file are not quoted with with " or ' for some reason. For example:

first_name, last_name, number
tom, cruise, 1
tom, hanks, 2

You can try Apache Commons CSV

try (CSVParser csvParser = CSVParser.parse(csv001, Charsets.UTF_8, CSVFormat.DEFAULT)) {
    DataSet ds002 = Stream.of(csvParser.iterator()).map(e -> Iterators.toList(e.iterator()))
            .headAndTail().map((h, t) -> t.toDataSet(h.get()));
    ds002.println();
}

Or you can also manually parse the CSV file(This could be the fastest way):

String delimiter = ", "; // which could be ',', Tab spaces or any string used to delimit the values in the CSV.
DataSet ds003 = Stream.of(csv001)
        .call(s -> s.map(e -> N.splitPreserveAllTokens(e, delimiter))
                .headAndTail().map((h, t) -> t.toDataSet(Arrays.asList(h.get()))));
ds003.println();

// or:
try (LineIterator iter = IOUtil.iterate(csv001)) {
    ds003 = Stream.of(iter)
            .map(e -> N.splitPreserveAllTokens(e, delimiter))
            .headAndTail().map((h, t) -> t.toDataSet(Arrays.asList(h.get())));
}
