Unable to read the message java.io.IOException: No content

Question

Getting the following Exception while reading a mail........
Caused by: java.io.IOException: No content
at javax.mail.internet.MimePartDataSource.getInputStream(MimePartDataSource.java:108)
at javax.activation.DataSourceDataContentHandler.getContent(DataHandler.java:805)

at javax.mail.internet.MimeMessage.getContent(MimeMessage.java:1396)
at com.test.services.inbound.readmail.BouncedMailReader.processBouncedMails(BouncedMailReader.java:151)
Line 151 is below
{color:#0000ff}*multipart = (MimeMultipart)msg.getContent();*
{color}
But when I manually copy the same mail back to "new" folder from "cur",then the read is successful.
Please suggest.

Sounds like Subbaraja may be right, there's no synchronization between the program that's
storing the messages in the files and your program that's reading the messages from the files.
If the program storing the message has only written half the message, and then you try to read
it, you're going to get errors similar to what you got. Adding the call to getMessageID may just
slow your program down enough to allow the writer to finish writing the message.
Of course, the "maildir" local store provider that you seem to be using should be synchronizing
with the other program that's writing the messages, so you might want to talk to whoever you
got the maildir provider from to see what's going wrong there.
