+        <description>
+            Non-thread safe singletons can result in bad state changes. Eliminate
+            static singletons if possible by instantiating the object directly. Static
+            singletons are usually not needed as only a single instance exists anyway.
+            Other possible fixes are to synchronize the entire method or to use an
+            [initialize-on-demand holder class](https://en.wikipedia.org/wiki/Initialization-on-demand_holder_idiom).
+
+            Refrain from using the double-checked locking pattern. The Java Memory Model doesn't
