This also applies to the JAVA programming language. Those versions of the language specification prior to JAVA 5 did not include support for generics. Therefore, refactoring tools had to evolve to modify their refactoring implementations according to the new language characteristics in order to assure the correct effects when transforming code containing generic definitions or using generic instantiations. This paper presents an evaluation of the behaviour of refactoring tools on source code that defines or uses generics. We compare the behaviour of five refactoring tools on a well known refactoring, Extract Method, and its implementation for the JAVA language. We distill the lessons learned from our evaluation into requirements that have to be taken into account by refactoring tools in order to fully conform to this new language feature.","PeriodicalId":307062,"journal":{"name":"2010 14th European Conference on Software Maintenance and Reengineering","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126677508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many tools have been proposed in the past. However, the many different output formats used by the tools make it difficult to compare their results and to improve their accuracy and performance through data fusion. In addition, all the output formats have been shown to have several limitations in both their forms and contents. Consequently, we develop DPDX, a rich common exchange format for DPD tools, to overcome previous limitations. DPDX provides the basis for an open federation of tools that perform comparison, fusion, visualisation, and–or validation of DPD results.","PeriodicalId":307062,"journal":{"name":"2010 14th European Conference on Software Maintenance and Reengineering","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123645796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Load tests generate vast amounts of performance data, which needs to be compared and analyzed in limited time across tests. This helps performance analysts to understand the resource usage of an application and to find out if an application is meeting its performance goals. The biggest challenge for performance analysts is to identify the few important performance counters in the highly redundant performance data. In this paper, we employed a statistical technique, Principal Component Analysis (PCA) to reduce the large volume of performance counter data, to a smaller, more meaningful and manageable set. Furthermore, our methodology automates the process of comparing the important counters across load tests to identify performance gains/losses. A case study on load test data of a large enterprise application shows that our methodology can effectively guide performance analysts to identify and compare top performance counters across tests in limited time.","PeriodicalId":307062,"journal":{"name":"2010 14th European Conference on Software Maintenance and Reengineering","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128900809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This holds independent of whether redundancy was created by copy&paste or by independent development of behaviorally similar code. Existing clone detection tools successfully discover syntactically similar redundant code. They thus work well for redundancy that has been created by copy&paste. But: how syntactically similar is behaviorally similar code of independent origin? This paper presents the results of a controlled experiment that demonstrates that behaviorally similar code of independent origin is highly unlikely to be syntactically similar. In fact, it is so syntactically different, that existing clone detection approaches cannot identify more than 1% of such redundancy. This is unfortunate, as manual inspections of open source software indicate that behaviorally similar code of independent origin does exist in practice and does present problems to maintenance.","PeriodicalId":307062,"journal":{"name":"2010 14th European Conference on Software Maintenance and Reengineering","volume":"342 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122280496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some examples are: physically relocating a data center, replacement of infrastructure such as migrating from an in-house broker to CORBA, moving to a new architectural approach such as migrating from client-server to a service-oriented architecture. At a high level, the goals of such an evolution are easy to describe. While the end goals of the evolution are typically captured and known, the key architecturally significant requirements that guide the actual evolution tasks are often unexplored. At best, they are tucked under maintainability and/or modifiability concerns. In this paper, we argue that eliciting and using architecturally significant requirements of an evolution has a potential to significantly improve the quality of the evolution effort. We focus on elicitation and representation techniques of architecturally significant evolution requirements, and demonstrate their use in analysis for evolution planning.","PeriodicalId":307062,"journal":{"name":"2010 14th European Conference on Software Maintenance and Reengineering","volume":"237 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115652414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We believe that there at least two main causes for this lack of adoption: (i) the lack of integration in mainstream IDEs and (ii) the lack of support for a continuous (daily) usage of QA tools. In this context we created INCODE as an Eclipe plug in that would transform quality assessment and code inspections from a standalone activity, into a continuous, agile process, fully integrated in the development life-cycle. But INCODE not only assesses continuously the quality of Java systems, it also assists developers in taking restructuring decisions, and even supports them in triggering refactorings.","PeriodicalId":307062,"journal":{"name":"2010 14th European Conference on Software Maintenance and Reengineering","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122620746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, reducing false-negatives in these techniques is a goal with strong practical relevance. This work presents a technique that uses both static and dynamic analysis of object-oriented source code to improve resulting impact estimates in terms of recall. The technique consists of three steps: static analysis to identify structural dependencies between code entities, dynamic analysis to identify dependencies based on a succession relation derived from execution traces, and a ranking of results from both analyses that takes into account the relevance of dynamic dependencies. Evaluation was performed through prototype development and a multiple-case quantitative case study that compared our solution against a static technique and a dynamic one. Results showed that our hybrid technique improved recall between 90 and 115% compared to the static technique, and between 21.2 and 39% compared to the dynamic one.","PeriodicalId":307062,"journal":{"name":"2010 14th European Conference on Software Maintenance and Reengineering","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122413293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
