- The page says the agent supports Windows, Linux, and macOS, with native library formats listed for each platform.
Field notes
The page describes a native agent attaching through JVMTI, with local-value capture also attributed to a BCI-shadow approach. Its example walks through a NullPointerException with stack frames, a decompiled source excerpt, and locals including a null value. The project says it handles exception storms through FULL, REDUCED, and COUNT modes; the supplied homepage evidence does not verify those capabilities in operation.
