Cloned from https://issues.jboss.org/browse/CLOUD-2286 , which implements the feature for openjdk and other images by adding the GC_CONTAINER_OPTIONS env:
Would be good to allow users to change the garbage collector when using the webserver images . Adding a different collector via JAVA_OPTS_APPEND does not take effect.
Currently the garbage collector is set in this script with no option to change it:
