+#### Renamed Rules
+
+*   The Java rule {% rule "java/errorprone/DoNotCallSystemExit" %} has been renamed to
+    {% rule "java/errorprone/DoNotTerminateVM" %}, since it checks for all the following calls:
+    `System.exit(int)`, `Runtime.exit(int)`, `Runtime.halt(int)`. All these calls terminate
+    the Java VM, which is bad, if the VM runs an application server which many independent applications.
