EE 9 Platform TCK connector failures due to duplicate installation of R-A services

The connector tests in the EE 9 platform TCK have 56 failures that stem from failures to deploy two of the rars the TCK deploys, whitebox-mixedmode.rar and whitebox-permissiondd.rar. Both fail to deploy with a failure message similar to this: 2020-10-29 15:01:48,363 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 10) MSC000001: Failed to start service jboss.ra.deployment.

I believe this is due to IronJacamar not handling completely its Version.V_20 that was added in JBJCA-1412 . There are a number of classes that check for Version.V_17 and adapt handling if that's the version. Version.V_20 is logically equivalent (EE 9 and EE 8 are not meant to have different behavior) so those same check should consider Version.V_20. If I change the ra.xml files in the two rars to use the 1.6 or 1.7 version and namespace but make no other changes to the configs the connector tests all pass.
