Simple Java Sampling Wrapper (SJSW) is a library that wraps the intristics of JVM profilers (the only one currently support is the async-profiler) and provides the implementation for building context call trees from profiler's JFR output that can be used for the analysis of performance or application's internal behavior.
This library was created as part of the implementation phase of the Computer Science Bachelor's Thesis: Examination of Performance Change Detection Efficiency Using Sampling and Instrumentation Techniques (Juozas Skarbalius, March 2025).
