Not more resources available in pool exception logged in Orient 1.6.4 plocal embedded database

[aruld]

I am seeing this exception in standard out. This happens after a hot reload from our play application. It usually happens right after Play runs its jobs which uses Orient database after a hot reload. We do close database after use in our application.
