  * Each Aspect will have an owner - the BaseProList it belongs to. ProLib Registry's endReadTrack() method will be modified to filter out Aspects which were read but also had their owner read. This will prevent an AutoTracker which reads let's say both a given BaseProList and one of its Aspects, to get updated multiple times. This will prevent "constant" AutoProperties which should get computed only once, to get updated more than 1 time.
 
+Another issue which could be fixed is the performance of the findMethodAnnotation(...) methods in the ProLib ReflectionUtil class.
+The
+{{{
+    public static <T extends Annotation> T findMethodAnnotation(Method m, Class<T> annotationClass);
+}}}
+simply maps a Class to some Method.
+Instead of doing this each time, a helper HashMap can be used to perform memoization of these queries.

+ On my machine, these optimizations led to the following results:
+ * 4-5 sec startup time reduction for the usage of Aspects.
+ * roughly the same for the memoization described above.
+
+ Prior these optimizations, startup time was ~25 sec.
