It would also be useful/interesting to include a test that checks every Serializable class (by  Invoking `ObjectStreamClass.lookup(clazz)`) in the Java runtime and reports any jfr events.  
Fixing them would be a separate task.  The compiler warnings from last year should have fixed most/many non-conforming classes.
