I know that, but "container_type" label is in hs_err / VM.info log. In addition, UL reports some metrics as "container" in spite of cgroups.
If it takes a long time to fix JDK-8261242, I want to fix log messages for cgroups for next LTS release at least. "container" messages may make the customer do extra work to collect / analyzer their system.
