As LCS Developer I'm not able to upgrade LCS portal based on Liferay Portal EE 6.2 to DXP SP6 (DE32)

Upgrade process ends up in stack overflow with recursive call to com.liferay.portal.language.LanguageResources#getSuperLocale

Source of issue which manifests during upgrade configuration-admin-web module is caused by GroupUpgrade process, where LanguageUtil is used in inappropriate way which doesn't complete superLocale resolution in LanguageResource class.
