Feature #8468: Remove $SAFE - Ruby master - Ruby Issue Tracking System
JRuby has not supported $SAFE for a long time, and the only complaints we've heard are from people that thought they needed $SAFE (and did not) or people who just happened to notice it was missing. We strongly support removing $SAFE, but I would like to help come up with a better (more fine-grained, more configurable, more reliable) security mechanism to replace it as well.
