How this group was decided

Every step below is a pure function of the event. The same event always produces the same group.

  1. 1 · Parse the stack trace

    5 frames parsed, 2 belong to the application. Only those decide the group — the same bug reaches the runtime through different framework paths depending on the request.

    • in-appcom.example.checkout.ReservationService.reserveReservationService.java:88
    • in-appcom.example.checkout.CheckoutController.submitCheckoutController.java:54
    • vendorjdk.internal.reflect.DirectMethodHandleAccessor.invokeDirectMethodHandleAccessor.java:103
    • vendororg.springframework.web.method.support.InvocableHandlerMethod.doInvokeInvocableHandlerMethod.java:255
    • vendororg.springframework.web.servlet.DispatcherServlet.doDispatchDispatcherServlet.java:1089

  2. 2 · Build the fingerprint input

    Line numbers are dropped so that editing a line above the throw site does not open a new group. Values inside the message are replaced with placeholders.

platform=java
service=checkout-api

frame=com.example.checkout.ReservationService#reserve
frame=com.example.checkout.CheckoutController#submit

  3. 3 · Hash it

    SHA-256 of the text above, truncated to 128 bits. The version is part of the group key: a future algorithm opens new groups rather than rewriting these.

Similar groups

Trigram similarity computed by Postgres against a GIN index. It catches what a fingerprint cannot — the same fault one refactor away from an existing group. No model is involved.
