Using custom image based on java11 doesn't work

[rdpa]

It appears that the operator sets some JAVA_OPTS to tune based on the java8 image, specifically -XX:+UseCGroupMemoryLimitForHeap. This option is not present in java 11, and so the JVM fails to start. I can't find a place to override these variables, or tell the operator not to set them.

Edit: Here is the offending line. Also note that setting -XX:MaxRAMFraction=1 is not advisable because it carries a high risk of getting the container OOMKilled.

Edit 2: The operator explicitly forbids JAVA_OPTS from being overridden

Hi @rdpa,

JAVA_OPTS is hardcoded now. It will be fixed in the next release. Could you provide your jenkins docker image because we support only jenkins:lts for now?

Cheers

Hi, sure. I was attempting to use the jenkins:lts-jdk11 image. Thanks for the response!
