"modern" and "obsolete" does not mean anything for those people.

("supported" and "unsupported" means something, but both Java and
Cobol are supported so that does not tip the scale any way)

But there are some realities that they are aware of:
- the developers they hire knows Java not Cobol
- almost any DB/MQ/cache comes with a Java client while few comes
   with a Cobol client
- the typical Java setup would be much more geared towards
   CI/CD than the typical Cobol setup
- there are around 32 million open source artifacts available
   for Java via Maven not for Cobol

There are serious reasons to wish to be on Java instead
of Cobol.

There are also very serious reasons to not wanting to rewrite
large applications!
