I've found "963304 - Native components check box is invisible when installing EAP 6.0.0 through jar installer." is fixed so we can move this from known issues to bug fixes category.
I have now moved the Release Notes entry for BZ963304 to "Bug Fixes". When an updated build of the Release Notes is available on Docstage I will move this ticket to ON_QA.
Updated document is now available at [1] for confirmation. [1] http://documentation-devel.engineering.redhat.com/docs/en-US/JBoss_Enterprise_Application_Platform/6.2/html-single/6.2.0_Release_Notes
Verified.
