Dynamic Fine-Grained Adaptation at Hands

The JavAdaptor and FiGA cases

Software is changed frequently during its life cycle. New requirements come and bugs must be fixed. To update an application it usually must be stopped, patched, and restarted. This causes time periods of unavailability which is always a problem for highly available applications. Even for the development of complex applications restarts to test new program parts can be time consuming and annoying. Thus, we aim at dynamic software updating (DSU) frameworks to update programs at run-time. JavAdaptor is a DSU framework for Java that (a) offers fine-grained dynamic updating, (b) supports schema changing, (c) introduces only minimal performance overhead, and (d) does not dictate the program architecture. JavAdaptor combines schema changing class replacements by class renaming and caller updates with Java HotSwap using containers and proxies. It runs on top of all major standard Java virtual machines. Updates often urge in critical situations and the system update could be challenging. Using run-time models as an interface for updating software at run-time can help developers manage the complexity of updating software while it is executing. The FiGA framework enables the updating of Java software at run-time through the use of run-time models consisting of UML class, activity and sequence diagrams. Changes to models are transformed to changes on Java source code, which is then propagated to the run-time system using the JavAdaptor DSU technology. The FiGA framework permits in-the-small software changes, i.e., changes at the code statement level, as opposed to in-the-large changes, i.e., changes at the component level that are the case in traditional models at run-time approaches.
Walter Cazzola (Ph.D.) is currently an associate professor at the Department of Computer Science of the Università degli Studi di Milano, Italy and the chair of the ADAPT research group. His research interests include reflection, aspect-oriented and context-oriented programming, dynamic software evolution, domain specific and general purpose languages (design and implementation) and language and software product lines. He is the designer of the mChaRM framework, of the @Java, [a]C#, @AspectJ, Blueprint programming languages or extensions and he is currently involved in the design of the Neverlang language workbench. He is also the designer of JavAdaptor and FiGA dynamic system updating (DSU) frameworks. He has written more than 100 technical papers and served in the programme committee of all the major conferences about his research interests. More information are available on his professional webpage.
