Struggling with disallowed symbols in filenames for files attached to JIRA issues


The closest issue I can find relating to this is Confluence only (CONF-22338) - which suggests it is related to Tomcat and double decoding... I'm admin for JIRA but I don't have access to the server where our instance of JIRA is installed so I don't know if this is relevant.

The problem we have in our instance of JIRA are filenames such as the following:

problems symbols+je.docx
problems symbols%20je.docx
problems symbols%2Bje.docx

cannot be downloaded (but can be uploaded) in JIRA issues, users just get a blank screen when trying to download them.

But the following are fine:

problems symbols%je.docx
problems symbols=je.docx
problems symbols%2je.docx

I can't find a definitive list of disallowed symbols for JIRA anywhere in Answers but I've informed our users to not use + symbols, but this is still causing a headache because they work all the time with Word documents from lots of sources with different filenaming conventions.

Any help would be greatly appreciated.

What do the logs say?


Thanks for your response, I ran the log scanner and there was 'Generic 'Internal Server Error' on JIRA page' but nothing specifically mentioning attachments. I don't have access to the application server logs so I can't view the logs directly.

Hard to answer then if you can't get the raw logs.
