RetryableErrorHandler.handleConversionError throws ArrayIndexOutOfBoundsException

[idahiron]

Hello Univocity Team,

It seems that handleConversionError throws an ArrayIndexOutOfBoundsException, when a CSV file contains only one field without commas in a record while the header have seviral columns.

The row[2] fails because of that:

Input CSV:

LastName, FirstName, Number, Date
Johnson, James, 00000, 2022-7-26
Smith

Unexpected error processing input row [Smith] using Processor com.univocity.parsers.common.processor.BeanListProcessor.

Original source: my app encounters an error when it processes row[column] = defaultValue;

protected final boolean handleConversionError(Throwable ex, Object[] row, int column) {
		if (row != null && row.length < column) {
			//expand row so column index won't make error handlers blow up.
			row = Arrays.copyOf(row, column + 1);
		}
		DataProcessingException error = toDataProcessingException(ex, row,  #column);

		if (column > -1 && errorHandler instanceof RetryableErrorHandler) {
			((RetryableErrorHandler) errorHandler).prepareToRun();
		}

		error.markAsHandled(errorHandler);
		errorHandler.handleError(error, row, context);

		if (column > -1 && errorHandler instanceof RetryableErrorHandler) {
			RetryableErrorHandler retry = ((RetryableErrorHandler) errorHandler);
			Object defaultValue = retry.getDefaultValue();
			row[column] = defaultValue;
			return !retry.isRecordSkipped();
		}
		return false;
	}

Thank you for your work on the excellent Univocity library.

I am having the same issue, if there are less characters in a file, the exception is thrown. Did you find any workaround?
