io.seata.rm.datasource.exec.LockConflictException: null

The payload names no files or tests. Start by comparing the demo's properties and YAML configuration while reproducing the Hikari connection-pool setup, then trace the transaction commit that raises LockConflictException. Done means the configuration or connection-pool cause is confirmed and a reproducible resolution is documented.
