OpenCSV not mapping JavaBeans with annotations

Question

I am using version 3.8 of OpenCSV library. I am using annotation to map the bean fields to the columns in the CSV file. I have it working to a point. It is failing when a date field is blank.

java.lang.RuntimeException: Error parsing CSV line: 1

The annotation for the specific bean field as "required=false" but it still does not work. Here is the JavaBean annotation where I am using the Java.Util.Date class:

@CsvBindByName(column="Sent On", required=true)
@CsvDate(value="MM/dd/yyyy HH:mm:ss a z")
private Date sentOn;

@CsvBindByName(column="Last Activity", required=false)
@CsvDate(value="MM/dd/yyyy HH:mm:ss a z")
private Date lastActivity;

@CsvBindByName(column="Completed On", required=false)
@CsvDate(value="MM/dd/yyyy HH:mm:ss a z")
private Date completedOn;

This is how I have created the CSV reader and parser:

    final char QUOTE_CHARACTER = '"';
    ClassLoader classLoader = getClass().getClassLoader();
    File newFile = new File(classLoader.getResource(fileName).getFile());
    CSVReader reader2 = null;

    FileReader fileReader2 = null;

    List myList = null;

     try {

        HeaderColumnNameMappingStrategy strat = new HeaderColumnNameMappingStrategy();
        strat.setType(My_Data.class);

        CsvToBean csv = new CsvToBean<>();

        final CSVParser csvParser = new CSVParserBuilder().withSeparator(delimiter)
                                                          .withQuoteChar(QUOTE_CHARACTER)
                                                          .withStrictQuotes(true)
                                                          .build();

        fileReader2 = new FileReader(newFile);

        reader2 = new CSVReaderBuilder(fileReader2).withCSVParser(csvParser)
                                                   .withVerifyReader(true)
                                                   .withKeepCarriageReturn(false)
                                                   .build();


         myList = csv.parse(strat, reader2);

Here is CSV file data:

"Subject","Status","Sender Name","Recipient","Sent On","Last Activity","Completed On","Completion Time (DD:HH:MM)","Created Date","Declined Date","Document ID","Reason for Declining","Expiration Date","Date Signed"
"MyCompany: Plan RCP Endorsements Select Bundle","Sent","ENV_PROD","SANDRA BULLOCK","7/21/2016 10:49:38 AM EST","7/21/2016 10:49:38 AM EST","","","7/21/2016 10:49:37 AM EST","","e05e53d8-e8bd-469e-a774-c0dec98481b2","","9/4/2016 10:49:38 AM EST",""

How I discovered this fault is walking through the source code. I am hoping others have face a similar issue and can give me a suggestion on how to get around this issue. I like this mapping approach as it saves me time and effort. The process is working by just reading the file into a List. The problem with this approach is I would have to write the factory process for the JavaBeans.

Suggestions are welcomed.

Thanks,

Russ
