  * A handler marked with this annotation is guaranteed to be invoked in a thread-safe manner, that is, no
- * other running message publication will be able to invoke this handler as long as it has not done its work.
+ * other running message publication will be able to invoke this or any other synchronized handler of the same
+ * listener until the handler completed. It is equal to wrapping the handler code in a synchronized{} block.
+ * This feature will reduce performance of message publication. Try to avoid shared mutable state whenever possible
+ * and use immutable data instead.
+ *
+ * Note: Unsynchronized handlers may still be invoked concurrently with synchronized ones
