Command: java source-file probe with current compiled persistence/application/shared classes and Spring transaction dependencies Working directory: /shared/codebase/clean-architecture-backend-template Executed at: 2026-08-29T08:01:29Z Source revision: a24ece9cf797f7ea647e33bf846b115208ed1ba5 Observation boundary: Supplies a custom JpaRetryPolicy that always fails and counts invocations to FullTransactionRetryCoordinator, then executes a valid TransactionProfile with its mandatory RetryProfile. This isolates whether the application-supplied policy participates in valid coordinator execution; it does not model a real database. --- stdout/stderr --- thrown=SERIALIZATION_FAILURE customPolicyCalls=0 workCalls=2 Exit code: 0
