Unfortunately, this workaround is unacceptable in many deployment 
environments. I would thus consider this a showstopping bug for Nashorn, 
and I hope it can be escalated.

(I understand that this is not the Nashorn project's "fault," but the 
bottom line is that Nashorn cannot be used in long-running production 
environments until this is solved.)
