Customizing Java options

[iromli]

Currently, Java-based container only support modifying heap size through MaxRAMPercentage option set by GLUU_MAX_RAM_PERCENTAGE environment variable. To have a full control of options passed to Java (i.e. -Xmx), we need to add ENV, i.e. GLUU_JAVA_OPTIONS.

An example of container entrypoint:

exec java \
    -server \
    -XX:+DisableExplicitGC \
    -XX:+UseContainerSupport \
    -XX:MaxRAMPercentage=$GLUU_MAX_RAM_PERCENTAGE \
    -Dgluu.base=/etc/gluu \
    -Dserver.base=/opt/gluu/jetty/oxauth \
    -Dlog.base=/opt/gluu/jetty/oxauth \
    -Dpython.home=/opt/jython \
    -Djava.io.tmpdir=/tmp \
    $(get_debug_opt) \
    ${GLUU_JAVA_OPTIONS} \
    -jar /opt/jetty/start.jar

All Java-based images have been updated to support new env var GLUU_JAVA_OPTIONS.
