Hello Guys,

After receiving 2 tickets with the same description, I tried to reproduce the error, and I successfully reproduced it easy enough:

• Have a zip file that contains a file with a single quote character in the name
• try to attach it to a ticket

The users get a illegal argument page. To workaround the issue, you have to remove the single quote within the zip file to succeed.

The error only happens with zip files - regular files with single quotes can be attached and viewed just fine, and also tar.gz files works as well.

Strangely enough, this behaviour only happens on JIRA 4.2, and in the previous versions, it runs smoothly.

Best Regards
