How to avoid the burst of classes loaded after a minute

[Houtman, Roland]

Dear Devs,

Nashorn loads a massive amount of classes after running for a minute.
Here I explained what I am doing and seeing:

I'm trying to get the cpu- and memory-usage as effective as possible.
What are the options to affect this behavior? 

Kind regards,
Roland
