Using expression-sandbox

[viebel]

I'd like to use an expression-sandbox for implementing secured mode in Klipse.

I have tried the naive approach suggested in https://blog.risingstack.com/writing-a-javascript-framework-sandboxed-code-evaluation/

Do you think that expression-sandbox could be helpful?

I have played with it a bit. The problem is that

Sandboxes are only allowed to return primitive values

and

You cannot set properties on a sandboxed object.
