Kostas Kloudas commented on FLINK-17745:
----------------------------------------
Hi all, from the removed code in the PR, we were traversing the user jar and we
were adding the found nested jars in classpath *only* if they were packaged in
a {{lib/}} folder. We were expecting a *specific structure* of the jar. See
the {{getContainedJarEntries()}} in the removed code.
Given that this feature was not documented, I am not sure if anyone is actually
using it. Do you have any such cases? If yes, then I agree that the code should
not be removed and I will close the PR.
> PackagedProgram' extractedTempLibraries and jarfiles may be duplicate
