Aspose Email Java – ICS file throwing exception - Value is too large

bing.liu · September 14, 2022, 5:28pm

Aspose and Java version: aspose-email-22.4.1-jdk16.jar

   Below is my code
import com.aspose.email.*;

    String path = "/tmp/myCalendar.ics";
    AppointmentLoadOptions alo = new AppointmentLoadOptions();
    alo.setIgnoreSmtpAddressCheck(true);
    appointment = Appointment.load(path, alo);


The myCalendar.ics is the client file made by Outlook which contains Japanese characters. 
And I don't have permission to use the client file to reproduce this exception. 
I made some sample ICS files with Japanese characters, couldn't reproduce it.
Hopefully, you may shed some light on the exception below.

@bing.liu

Could you please ZIP and attach your ICS file here for testing? We will investigate the issue and provide you information on it.

Thanks for your reply. I am unable to upload any file from my computer due to security reason. I open my ICS file with text editor and paste below. You may save it as .ics file and use it to test it. I tested with different version of Aspose (22.4 and 22.6). The same exception occurred ( see the stack trace posted above). This ICS file was created by Outlook 10. My programs work well with ICS created by Outlook 16.

The original ICS file contains Japanese characters which I thought the reason to cause the exception. After I removed them, replaced with English letter, the same exception happened. This ICS created by older version Outlook may not work well with Appointment API on VEVENT. This issue happened to our client. Please provide the fix or workaround. Thanks.
