| Abstract | The development of instrumentation-based dynamic analyses for Java bytecode is enabled by various bytecode rewriting frameworks. Those frameworks are all implemented in Java. This complicates their use for developing full-coverage analyses that not only observe application code, but that also observe the execution of the complete Java class library. Moreover, it makes it hard to avoid perturbation due to the Java code of the instrumentation tool interfering with the Java code of the observed program. So far, workarounds for these problems required either statically instrumenting the runtime library or running a separate JVM as an instrumentation server. This paper solves this problem. It introduces JNIF, the first complete bytecode rewriting framework implemented in native code. JNIF can be used in a JVMTI agent to create isolated, full-coverage, in-process dynamic instrumentation tools. JNIF is written in C++ and has an object-oriented design familiar to users of Java-based rewriting libraries. JNIF is able to decode, analyze, edit, and encode Java class files. This includes the generation of stack maps required by split-time verifiers of modern JVMs. Our performance evaluation shows that JNIF is often faster than the most performant competitive approach based on ASM. |

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.
