File names in attachments are truncated just before the ";" character

The extension is also lost but the file contents is ok.
I saw some links with other issues but could not find exactly the same issue: JRA-6141, JRA-5481 ... _{possible others}

As a requirement I would state:

1. The system should allow to attach any file to Jira
2. any file that is valid for the operating system should also be valid for Jira
