Change -Xmx and Xms settings for EAP on Openshift -

i'm trying change default settings openshift eap images (by default container starts jvm -xms1303m -xmx1303m). i've tried adding settings java_opts_append, not effective. can see it's being appended @ end of java_opts, inspecting jvm process, can see defaults still being used. idea ? thanks

setting jvm resource limits through java_opts_append won't work. have set resource limits container. example, settings resource limits 1gb, allow portion of used application server mx , ms limits (typically half of resource limits container need dedicate resource limits os)
