| Abstract | Exception mechanisms help to ensure that a program satisfies the important robustness criterion of dependency safety: if an operation fails, no code that depends on the operation's successful completion is executed anymore nor will wait for the completion. However, the exception handling mechanisms available in languages like Java do not provide a structured way to achieve dependency safety. The language extension failbox provides dependency safety for Java in a compositional manner. So far, there only exists an implementation of failbox in Scala. It requires the assumption of absence of asynchronous exceptions inside the failbox code. In this paper, we are the first to provide an implementation without the above mentioned assumption, this time in Java. First, we present and discuss a direct reimplementation of failbox in Java that is still restricted. Then, we show that using uncaught exception handlers the earlier assumption can be essentially weakened to only concern code before setting the thread handler. Finally, we provide an implementation using the Java native interface that completely removes the assumption. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
