Are Util features supported? * JavaCard side channel?

Question

I am wondering if Util features work. * in JavaCard, usually on the side channels. Are there some JavaCards that have side channel resistant Util. * Functions?
I looked at some JavaCard public security targets. But no one has security requirements for the listed Util. * Functions.

To achieve side-channel resistance in Java itself without the help of native code seems to be difficult, if not impossible. Therefore, a JavaCard must have side channel resistant Util features. *, Correctly?
