However I've re-opened this bug (I do not understand why it was closed) and
assigned to someone might be able to find time to take care of it.

This is a widespread issue and very frustrating issue, see:

Frankly, I don't understand how X works at all, or how this issue
arises. However, this same workaround was applied to Mozilla in 2010:
https://hg.mozilla.org/releases/mozilla-1.9.1/rev/62f3d28797e2, and I
don't see any reasonable behavior that having this workaround in place
would break. The workaround works by simply skipping native formats
that don't have a name.
Verified to work by running IntelliJ Clion under the modified VM and
verifying that paste from my terminal, which previously did not work,
now works. I'm not familiar with OpenJDK unit testing conventions, but
I believe this change falls under the "highly platform-dependent"
exception.
