You're completely wrong.

Jaybird is present in server filesystem.

User can upload whole Jaybird to database, yes, but it will be unusable:
- Classloader will load Jaybird classes from filesystem
- User can rename Jaybird, yes, but in the database it does not have
permissions as the code in the filesystem

So only people with filesystem rights can compromise the server, and by
default FB/Java does not allow this.
