+/**
+ * It is crucial that BeforeClass inits logging subsystem.
+ * If  logging subsytem of itw is enabled from itw, then junit's classloader do not
+ * see it. And so when is junit manipualting with logging, then it creates new (second!)
+ * static instance. On opposite, if junit creates the instance, then itw see this one.
+ *
+ * Explanation is that junit classloader (fresh for each test-class)  is creating
+ * special classlaoder for itw (or better itw is creating its own one). The itw 
+ * classlaoder is then branch...or leaf of junit classlaoder. So any class loaded
+ * by junit classlaoder is visible from itw, but not vice verse.
