The old COBOL crap is more likely to have been implemented by someone with a clue.

The “new” systems are usually aping the old system behavior. In one case, I ran into a system where some company converted COBOL transactions into Java with some sort of automated tool to put the legacy system “on the internet”.

I have no idea what that means, for newer is not necessarily more supportable. Who knows what the system is - maybe they had a multi-million dollar SAP implementation to manage prisons, and now you’re looking for functional support of that platform after it was customized all to hell, you need a-team SAP resources, not the new kid at Wipro... I can only imagine what’s behind that curtain. It’s the government so I imagine the worst.
