Hi Matthias, If you're interested in doing FS attachments, I absolutely recommend doing it right at the beginning because then you can avoid the migration process where your attachments are pulled up from the DB and placed into the FS.
You can catch errors in groovy as in java but I don't think that will help you here. I would do this by posting the attachment up using curl or the like because I'm not sure if doc.addAttachment() has been optimized for streaming. My biggest recommendation, especially since you're using HSQLdb is to enable FS attachments right away so you only have to migrate the attachments which are part of XWiki and all of your attachments will go strait to the filesystem.
