In order to get in the fix for https://issues.redhat.com/browse/DBZ-8447 QOSDK will need to be updated (from 6.7.x to 6.9.x). However, there seems to be a another bug

QOSDK is using fabric8 client's CRD generator and switched to v2 in 6.8.0. Unfortunately v2 is broken when default value for attribute is used as it only writes these default values into the spec as String regarding the actua type, resulting in invalid CRD.

TLDR: We need to update QOSDK. However we need to wait for 6.9.1 where workaround will be available for specific component – which potentially cost all 6.8.x versions to generate broken CRDs.
