They also explicitly require Java 7 bytecode, a single literal JDBC URL including MODE=DB2 and /app/output/bankdb, runtime usage of that URL, and deterministic re-run outputs. The tests enforce these explicitly stated requirements and the job passes those meta-constraints; only exceptions.csv content differs. Given the detailed instructions for exception reasons and the consistent failure pattern, this points to an implementation error (e.g., reason precedence, duplicate handling, or ordering) rather than insufficient or ambiguous task instructions. Therefore, the failures are due to agent implementation limitations, not missing specifications."
