Disable equals verifier ranges

[breedx-splk]

Supersedes #7319.

We only have a few places where we use the EqualsVerifier, so can we just prevent those tests from running with older JDKs? Is this a reasonable approach/compromise?

Hrmph. It looks to have passed on 8 but is failing on 11, seemingly due to the module system.

Maybe I don't know how to work around this after all. 😭
