Java Runtime 1.8 u241: The Unofficial "Bridge" Version You Need to Know

Introduction: A Forgotten Titan in the Java Update Cycle

It is not the most secure (that title goes to later updates like 8u301 and beyond), nor is it the most innovative.

This rejects all deserialization unless explicitly whitelisted. It prevents the majority of RCE attacks on 8u241. java runtime 1.8 u241
