Last December, Log4Shell shortened the nights of many people in the JVM world. Worse, using the earthquake analogy caused many aftershocks after the initial quake. I immediately made the connection between Log4Shell and the Security Manager. At first, I didn’t want to write about it, but I’ve received requests to do so, and I couldn’t walk away. Hey @nicolas_frankel, isn't the #Log4j-Exploit the perfect argument against deprecation of the Java SecurityManager?!
