What is wrong and what can be done to avoid this situation?

What is wrong? Nothing.

What can be done to avoid it? Nothing! :)

Nothing is really wrong with Hercules OTHER than possibly the fact that it
does not currently support that particular CCW opcode.

If we could locate documentation somewhere that explains what that
particular CCW opcode is (what it does and how it's used), then we *might*
be able to MAYBE add support for it. (Maybe)

But since we don't have the documentation for it and thus have no idea what
it does or how it's used, that makes it kind of difficult/impossible for us
to support it. ;-)

As Jay Maynard explained in his reply, it's not uncommon for IBM to update
their operating system to issue new commands to devices that THEY (IBM) know
are supported (by *real* 3390s) but which are not publicly documented
anywhere. THEY (IBM) probably have internal documentation that explains it,
but it's not something they wish to make public for whatever reason.

As you've already noticed however, supporting it is apparently not that
critical though, since the system appears to run just fine without it, so my
only advice to you would be to simply ignore it.
