The tmp folder in IG instance dir is growing at each startup, fulfill of a lot of empty folders named groovy-script-cache-<number>. This is not really a bug as the size won't have any impact but could(I know, sounds impossible but?) impact folder size limit in very specific deployments.
The system temporary folder is usually deleted after reboot but this require to modify the tmp folder in the admin.json (https://ea.forgerock.com/docs/ig/reference/index.html#AdminHttpApplication)
- Open question is, should it be the responsability of IG to delete those temporary folder when closing it?
