`gem-check` fails with Ruby 4.0.0_preview2

Hi,

I'm testing jruby-openssl with Ruby 4.0.0_preview2, and I'm seeing the following error:

More specifically:

Unexpected error in ruby require test for 'openssl/pkey' [1]: /usr/lib/ruby/4.0.0+0/openssl/pkey.rb:11:in '<module:PKey>': uninitialized constant OpenSSL::PKey::PKeyError (NameError)

Ruby 4.0 is scheduled to release on Christmas and it would be great if jruby-openssl could support it.

Thanks.

The gem is intended for JRuby, not sure why anyone would need this loading under MRI aligned with the 4.0 release.

Is this some kind of tooling or a research use-case?

@kares Apologies for the noise; I'm going through our distro's Ruby packages and noticed this one was failing, but didn't give it much though. I won't include this package in the batch of Ruby 4.0 modules.
