@XComp , thanks for your detailed comments for the refactoring. Based on your finding, I thought that: 1. `PythonBasedPackagedProgramRetriever` is indeed a `JarFilePackagedProgramRetriever` with a specific `jarFile` and `jobClassName`, which could be removed and pass in these specific parameter values in `JarFilePackagedProgramRetriever`. 2. `PackagedProgramRetriever` implementation could be similified by introducing interface `EntryClassInformationProvider` providing `getJarFile()` and `getJobClassName()` as methods. -- This is an automated message from the Apache Git Service.
