  • Hello, Since upgrading to JIRA 3.6 Enterprise (standalone) over the weekend, the e-mail handler that helps create and comment on issues has a problem where it keeps posting the same comments over and over again. From what I see, the user replies to an e-mail to add a comment made in a reported JIRA issue, but it appears that JIRA is not cleaning up the message off from the mail server once it processes. Becaus of this, we keep getting the same message over and over again until I can manually delete it off myself from the mail server. Looking at the log, here's what I see: 2006-05-05 07:22:56,793 WARN [jira.issue.managers.DefaultAttachmentManager] Creating attachment without a file. Aborting 2006-05-05 07:22:56,825 ERROR [service.util.handler.AbstractMessageHandler] Exception while creating attachment for issue IQ-3400: java.lang.NullPointerException java.lang.NullPointerException at com.atlassian.jira.issue.history.ChangeLogUtils.createChangeGroup(ChangeLogUtils.java:85) at com.atlassian.jira.issue.util.DefaultIssueUpdater.doUpdate(DefaultIssueUpdater.java:55) at com.atlassian.jira.service.util.handler.AbstractCommentHandler.addChangeHistoryItem(AbstractCommentHandler.java:122) at com.atlassian.jira.service.util.handler.AbstractMessageHandler.createAttachmentWithPart(AbstractMessageHandler.java:255) at com.atlassian.jira.service.util.handler.AbstractMessageHandler.handleMultipart(AbstractMessageHandler.java:209) at com.atlassian.jira.service.util.handler.AbstractMessageHandler.createAttachmentsForMessage(AbstractMessageHandler.java:192) at com.atlassian.jira.service.util.handler.AbstractCommentHandler.handleMessage(AbstractCommentHandler.java:90) at com.atlassian.jira.service.util.handler.CreateOrCommentHandler.handleMessage(CreateOrCommentHandler.java:100) at com.atlassian.jira.service.services.mail.MailFetcherService.run(MailFetcherService.java:184) at com.atlassian.jira.service.JiraServiceContainerImpl.run(JiraServiceContainerImpl.java:61) at com.atlassian.jira.service.ServiceRunner.execute(ServiceRunner.java:48) at org.quartz.core.JobRunShell.run(JobRunShell.java:191) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:516) 2006-05-05 07:22:56,825 WARN [service.util.handler.AbstractCommentHandler] Exception creating comment null java.io.IOException at com.atlassian.jira.service.util.handler.AbstractMessageHandler.createAttachmentWithPart(AbstractMessageHandler.java:262) at com.atlassian.jira.service.util.handler.AbstractMessageHandler.handleMultipart(AbstractMessageHandler.java:209) at com.atlassian.jira.service.util.handler.AbstractMessageHandler.createAttachmentsForMessage(AbstractMessageHandler.java:192) at com.atlassian.jira.service.util.handler.AbstractCommentHandler.handleMessage(AbstractCommentHandler.java:90) at com.atlassian.jira.service.util.handler.CreateOrCommentHandler.handleMessage(CreateOrCommentHandler.java:100) at com.atlassian.jira.service.services.mail.MailFetcherService.run(MailFetcherService.java:184) at com.atlassian.jira.service.JiraServiceContainerImpl.run(JiraServiceContainerImpl.java:61) at com.atlassian.jira.service.ServiceRunner.execute(ServiceRunner.java:48) at org.quartz.core.JobRunShell.run(JobRunShell.java:191) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:516) The same block appears over and over again in the log, until I remove the offending message from the mail server. We never had any problems before JIRA 3.6 and I don't see anything special about the e-mail message that causes it to get "stuck" in the mail queue since it was just a comment with no attachments. Any help is appreciated. Nordy Isaac

  • Attachment creation failure will cause a _NullPointer_ exception when attempting to create a change item for the attachment in the history of the issue. This results in the message handler looping over the mail indefinitely as the processing never completes.

Possible Culprit Commit cc920660309f76fbf94a1be86f03c779e1fd740c h4. Cause of exception In file DefaultAttachmentManager.java on line 408/409 an attachment is create using the createAttachment function found on line 412. This function can return null, e.g. if the file or filename is null, therefore on line 409 when they try to call getId on the variable 'attachment' a null pointer exception is thrown as attachment is null. h4. Advice CreateAttachment functions need to be cleaned up, I could not understand what was going on as there are 10 createAttachment functions and so could not figure out a workaround, therefore pushing this quickly would be appreciative for the customer.
