In order for Parca Agent to be able to make sense of the just-in-time compiled code by the Java VM, the Java process needs to comply to the linux kernel perf jit-interface. To do this, currently users need to start their java process with two flags -XX:+PreserveFramePointer and -agentpath:/your/path/to/libperfmap.so where the libperfmap.so agent can be downloaded here.

Checkout the demo example for more details.
