Additional information

I guess this is because of the call to Class#desiredAssertionStatus since method calls in java.lang.Class are not allowed. I think it would make sense to allow that specific method.

Thank you for your report. It is actually a feature: many operations are not allowed in the Playground:most IO, threading, Swing, and some others.

@JosePaumard Yes I know that many things are not allowed but I would argue that a language feature like asserts which doesn't need any OS interactions has little reason to be blocked.

I understand that reflection is blocked in general but I wanted to request asserts/Class#desiredAssertionStatus to be unblocked specifically.
