OpenJ9 failing -Ptest #7470
Description
The OpenJ9 CI job has been failing for some months with the following failure:
Error: Tests run: 7, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 3.149 s <<< FAILURE! - in org.jruby.test.TestLoadService
Error: org.jruby.test.TestLoadService.testRequireSocket Time elapsed: 0.[271](https://github.com/jruby/jruby/actions/runs/3527450787/jobs/5916533897#step:5:272) s <<< ERROR!
org.jruby.exceptions.LoadError: (LoadError) no such file to load -- io/wait
But attempting to run locally with an OpenJ9 Java 8 from today, I get an unexpected classfile version mismatch:
[INFO] --- exec-maven-plugin:3.0.0:exec (invoker-generator) @ jruby-base ---
Exception in thread "main" java.lang.UnsupportedClassVersionError: JVMCFRE199E bad major version 53.0 of class=com/jcraft/jzlib/GZIPInputStream, the maximum supported major version is 52.0; offset=6

I will be ignoring failures in the build for now.
