Can't view attachments after updating to JIRA Service Management 4.15

Jason Yeung_2zffgc

Hi,

I recently updated my JIRA to 8.15 and Jira Service Management to 4.15. After the update, the attachments in my issues are no longer accessible. The steps are:

go to the attachments section of an issue:

When I click on the link, I get the following:

I could still download the attachment. I was wondering if there's a way to check what could be causing this? It worked fine before the update.

Sincerely,

Jason

Hi @Jason Yeung

Please check whether these files are present in the folder jira/atlassian-jira/WEB-INF/classes/com/atlassian/jira/web/servlet

ViewThumbnailServlet.class

abstractViewFileServlet.class

ViewAttachmentServlet.class

If not present add it from the previous backup copying each files to the location I have specified.

Please let me know if it solved the issue.

Thanks,

Pramodh

Hi @Jason Yeung,

Have you updated all the installed apps to the latest compatible version?
You can try to use a different browser or Incognito/Private mode to rule out anything to do with the web browser.
If you have a reverse proxy, you might want to bypass the proxy and see if the issue still persists.

Hi @Pramodh M ,

I copied the 3 files from an old backup to the new installation. It didn't fix the problem. I was wondering would I need to restart the JIRA service in order for it to take into effect?

Hi @mogavenasan ,

There were some installed apps that are not compatible with JIRA 8.15. I'm waiting for the developer to respond. I tried different browsers and the problem persists.

You can disable all the installed apps to rule out them; Disabling and enabling apps.

Hi @Pramodh M ,

I copied the files and restarted the JIRA service. Unfortunately JIRA didn't come up for me. I get the following error:

Restart JIRA2 error.JPG

When I removed the 3 files and restarted JIRA service, the site came up file, though the attachments didn't work. My JIRA 8.15 installation didn't contain those 3 files and I copied them from an old backup. It was version 8.5.3. I was wondering if there is something else I could check to get the attachments working?

Just for my clarification - is Atlassian omitting code from newer versions which can result in failed in-place upgrades which they advertise as supported?

If so - why are they not at least providing a JAR for these classes that one could deploy to resolve the issue quickly?

Also begs the question of what other pieces of code may have been "omitted", and what their impact may be that we're just not being affected by so egregiously ...

Hi @Diego Rivera

This was in Older version, its resolved in latest version and even in LTS latest version.

Thanks,

I have 8.19.0 and it's still affected, verified. I had to put the files in a JAR and put it in the WEB-INF/lib directory via Docker magic.

If you're referring to 8.19.1 - it's available(ish) in Docker Hub already but not tagged consistently so I'm going to wait a few days.

It's a shame it took so long to fix such an egregious mistake, though.

Cheers!

Nope. Spoke too soon.

I can confirm that the container tagged with 8.19.1-jdk11 (which is identical to 8.19.1-ubuntu-jdk11, digest 96a85db0b2cc), available in Docker Hub, is 100% afflicted with this issue.

Cheers.

I just had this issue and this is what support sent me.
