**Issue Evaluation**
Category: `type/bug` | Status: **Confirmed**
The reported issue has been verified against the current codebase. Three
distinct option-declaration mismatches exist in the `tools` module:
1. **`ConsumerSubCommand`**: `-i` is read via `hasOption('i')` /
`getOptionValue('i')` but never registered in `buildCommandlineOptions`. The
per-client query branch is unreachable dead code; `DefaultParser` rejects the
flag before `execute()` runs.
2. **`ResetMasterFlushOffsetSubCommand`**: `-b` and `-o` are declared
`setRequired(false)` but read unconditionally with `.trim()` and
`Long.parseLong()`. Omitting either option causes `NullPointerException`.
3. **`DecodeMessageIdSubCommand`**: `-i` is declared `setRequired(false)`
but read unconditionally. Omitting the option causes `NullPointerException`.
**Root Cause:** Option declaration in `buildCommandlineOptions` does not
match the keys consumed in `execute()`. No null-checks guard the reads.
**Impact:** `mqadmin` CLI — three subcommands crash or reject valid input.
**Severity:** medium (CLI usability; no data-path impact)
An automated fix proposal will be generated. Reply `/approve` to proceed
