AI migrated legacy COBOL programs to Java, bugs included
This effort is often complicated by the lack of test data and the difficulty of validating all corner cases. When routing boundaries are reached, an analyzer identifies a Locked Paragraph: a condition preventing deeper exploration. The generated Java matched the COBOL reference under deterministic parity checks in all accepted test cases.
