Description

Error when add multiple attachments in AttachmentMessage to marshal as mimeMultipart.

 

Example code:

.process(e ->

Unknown macro: { AttachmentMessage am = e.getMessage(AttachmentMessage.class); am.addAttachment("front-image-file", new DataHandler(new FileDataSource(...))); am.addAttachment("back-image-file", new DataHandler(new FileDataSource(...))); }

)
.marshal()
.mimeMultipart()

 

Checking class MimeMultipartDataFormat I see it is removing attachment during iteration:

for (Map.Entry<String, Attachment> entry : exchange.getIn(AttachmentMessage.class).getAttachmentObjects()
.entrySet()) {
...
exchange.getMessage(AttachmentMessage.class).removeAttachment(attachmentFilename);
