'Caused by: com.sun.mail.util.FolderClosedIOException: null
I am using apache camel to monitor the incoming email to the inbox. After receiving the email the content (attachment) is being consumed. To consume the attachment in the email I used the code ilusterated on the apache camel homepage
https://camel.apache.org/components/3.16.x/mail-component.html
For some reason I am getting the following error:
Caused by: com.sun.mail.util.FolderClosedIOException: null
Code
@Component
public class EmailPollingRoute extends RouteBuilder {
static final Logger LOGGER = LoggerFactory.getLogger(EmailPollingRoute.class);
@Override
public void configure() throws Exception {
//@formatter:off
from("direct:processPollingEmail")
.routeId("routeId_EmailPollingRoute")
.pollEnrich("imaps://imap.web.de?username=XXXX&password=XXXXX&unseen=true&subject=FK100 - daily")
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
AttachmentMessage attachmentMessage = exchange.getMessage(AttachmentMessage.class);
Map<String, DataHandler> attachments = attachmentMessage.getAttachments();
if (attachments != null && attachments.size() > 0) {
for (String name : attachments.keySet()) {
DataHandler dh = attachments.get(name);
// get the file name
String filename = dh.getName();
if(filename != null && filename.endsWith(".csv")){
byte[] data = exchange.getContext().getTypeConverter()
.convertTo(byte[].class, dh.getInputStream());
LOGGER.info("data: " + data);
// write the data to a file
FileOutputStream out = new FileOutputStream(filename);
out.write(data);
out.flush();
out.close();
}
}
}
}
})
.to("log:newmail")
;
//@formatter:on
}
}

Solution 1:[1]
After adding the closeFolder and disconnect options I could ride of the error
.pollEnrich("imaps://imap.web.de"
+ "?username=XXXXX&"
+ "password=XXXXX&"
+ "unseen=true&"
+ "closeFolder=false&"
+ "disconnect=false&"
+ "subject=FK100 - daily")
