CsvBeanReader.read() does not reliably detect EOF

[atnak]

CsvBeanReader.read() is documented to return null after the last item.

Instead, it fails attempting to parse an invalid line.

BeanListHandler.load() also suffers from this problem.

How to reproduce

public static class Foo {
    int x;
    public int getX() { return x; }
    public void setX(int x) { this.x = x; }
}

{
    Path file = Files.createTempFile("bean_test", ".csv");

    try (CsvBeanWriter<Foo> beanWriter = CsvBeanWriter.newInstance(
            new CsvWriter(Files.newBufferedWriter(file)), Foo.class)) {
        beanWriter.write(new Foo());
    }

    try (CsvBeanReader<Foo> beanReader = CsvBeanReader.newInstance(
            new CsvReader(Files.newBufferedReader(file)), Foo.class)) {
        System.out.println(beanReader.read().getX());
        System.out.println(beanReader.read());    # java.lang.NumberFormatException: For input string: ""
    }
}

Possible workaround

for (;;) {
    List<String> values = beanReader.readValues());
    if (values == null) {
        break; // EOF
    }

    if (values.size() == 1 && values.get(0).isEmpty()) {
        continue; // empty line
    }
    beanReader.toBean(values);
}
