A General Approach to Modeling Java']Java Framework Behaviors

Interprocedural static analysis tools such as security analyses need good call graphs, which are challenging to scale for framework-based applications. So most tools model rather than analyzing frameworks. These models are manually crafted to capture framework semantics crucial for the particular analysis, and are inherently incomplete. We propose a general approach to modeling Java frameworks. It is not limited to any framework or analysis tool, therefore, highly reusable. While a generic approximation can be noisy, we show our carefully-constructed one does well. Experiments on Android with a client taint analysis show that our approach produces more complete call graphs than the original analysis. As a result, the client analysis works better: both precision (from 0.83 to 0.86) and recall (from 0.20 to 0.31) are improved.
