134-138:⚠️ Potential issue | 🔴 CriticalChange field types from
JobOperatortoJobLauncher;JobOperator.run(Job, JobParameters)does not exist in Spring Batch 5.x.In Spring Batch 5.x (used with Spring Boot 4.0.0), the
run(Job, JobParameters)method belongs toJobLauncher, notJobOperator. TheJobOperatorinterface usesstart(String jobName, Properties parameters)for launching jobs by name. Your fields namedasyncJobLauncherandsyncJobLaunchershould be typed asJobLauncher, notJobOperator. The current code will not compile.

- Line 97: Change the misspelled word "Sometimetimes" to "Sometimes" in the
README line that currently starts with "Sometimetimes mockintosh venv..." so the
sentence reads "Sometimes mockintosh venv doesn't work correctly by incompatible
version of `markupsafe`, install a compatible version with the". Ensure only the
single-word typo is corrected and preserve the rest of the sentence and
surrounding formatting.

- Around line 64-71: manualDefinedJobs stores a reference to defaultParams which
is later mutated by launchAllNonAutoDetectedJobs via
defaultJobParams.put("DATE", ...) and put("ATTEMPT_NUMBER", ...) causing
shared-map corruption; fix by cloning the stored or mutated maps so mutations
don't affect the original defaults: when preparing params in
launchAllNonAutoDetectedJobs, create a new map from defaultJobParams (e.g., new
HashMap<>(defaultJobParams)) and then add DATE/ATTEMPT_NUMBER to that copy (or
alternatively store copies into manualDefinedJobs when calling
manualDefinedJobs.put("job1", ...)), ensuring defaultParams remains immutable
across launches.

59-70: Minor: Spotless plugin version and status may drift.Line 61 hardcodes specific versions ("version 2.43.0", "version 1.22.0") and states the plugin is "currently temporarily disabled." These details will become stale if
pom.xmlchanges. Consider referencing thepom.xmlas the source of truth rather than duplicating version numbers here.fr-batch-service/README.md (1)
51-61: Consider renaming "Job1" to "Job 1" for readability.The static analysis tool flagged "Job1" as a potential spelling issue. Using "Job 1" (with a space) reads more naturally in a heading.

140-152: Consider extracting repeated exception-handling block.The identical four-catch pattern (lines 140–152, 182–194, 238–250, 305–317) is duplicated across every launch method. A small helper that accepts a
Callable<JobExecution>and returns an error string (or empty) would eliminate this duplication.fr-batch-service/src/test/java/com/fronzec/frbatchservice/batchjobs/JobsManagerServiceTest.java (1)
70-74: Redundant assertion —containsKeyis already covered byassertNotNull(result.get(...)).Line 73 adds no value after line 71. If
get("TestJob")returned non-null, the key necessarily exists.♻️ Remove redundant assertion
assertEquals(1, result.size()); assertNotNull(result.get("TestJob")); - // The result contains the job.toString() value which is set by the mock - assertTrue(result.containsKey("TestJob"));

166-178:⚠️ Potential issue | 🟠 Major
runningNumberis nullableInteger— potential NPE at line 178.
launchAllNonAutoDetectedJobs(line 109) usesint(primitive), so it's null-safe. Here,Integerallowsnullto slip through —runningNumber.toString()at line 178 would throw an NPE. Either:
- Add
Objects.requireNonNull(runningNumber)alongside the existingdatenull check at line 168, or- Change the type to
intto match the other method.Also, this method uses
"RUNNING_NUMBER"whilelaunchAllNonAutoDetectedJobsuses"ATTEMPT_NUMBER"for what appears to be the same concept. Consider unifying the parameter key.🐛 Suggested fix
public HashMap<String, String> launchAllJobsPreloaded( - LocalDate date, final Integer runningNumber) { + LocalDate date, final int runningNumber) { Objects.requireNonNull(date);If
Integermust be kept (e.g., for deserialization), add:Objects.requireNonNull(date); + Objects.requireNonNull(runningNumber);

63-83: Extract hardcoded job names and parameter keys into named constants.Lines 67-68 use
"paramname"/"paramvalue"and line 70 uses"job1"as raw literals. These strings also appear conceptually tied to repeated keys like"DATE","ATTEMPT_NUMBER", and"RUNNING_NUMBER"used later in the file. Pulling them intoprivate static final Stringconstants avoids typo-induced bugs and makes the intent self-documenting.The logging improvements and the TODO for dynamic configuration are a nice touch.
♻️ Suggested constant declarations (add near line 38)
private static final Logger logger = LoggerFactory.getLogger(JobsManagerService.class); + + private static final String PARAM_DATE = "DATE"; + private static final String PARAM_ATTEMPT_NUMBER = "ATTEMPT_NUMBER"; + private static final String PARAM_RUNNING_NUMBER = "RUNNING_NUMBER"; + private static final String PARAM_DESCRIPTION = "DESCRIPTION";As per coding guidelines, "Avoid magic numbers and strings; use named constants or enums instead of hardcoded literal values."
85-93: Public methods exposeHashMapas return type — preferMapinterface.The changed method signatures at lines 85, 90, and 166 return
HashMap<String, String>. MethodsasyncRunJobWithParamsandsyncRunJobWithParamsin the same class already returnMap<String, String>. Returning the interface type keeps the API consistent and avoids coupling callers to a concrete implementation.♻️ Suggested change (apply similarly to other methods)
- public HashMap<String, String> launchAllNonAutoDetectedJobsAsync( + public Map<String, String> launchAllNonAutoDetectedJobsAsync( LocalDate date, final int runningNumber) {
36-61: Consider making constructor-injected fieldsfinal.Fields
asyncJobLauncher,syncJobLauncher,beanFactory,jobsList,jobRepository, andmanualDefinedJobsare assigned once in the constructor and never reassigned. Marking themfinalenforces immutability and signals intent. This is pre-existing, so deferrable.

Run the container as a non-root user.
The image currently runs as root by default, which weakens container security posture.
