[EAP] Support and dynamically configure Java 8 metaspace size settings

    XMLWordPrintable

Details

    • CLOUD Maintenance Sprint 3

    Description

      The xpaas EAP based images currently default to using OpenJDK 8 which uses Metaspace instead of PermGen. Should the xpaas images using EAP 6.4.x provide default size settings for MetaspaceSize and MaxMetaspaceSize? EAP 7 provides default metaspace size values in standalone.conf. Should the metaspace size values be dynamically defaulted like permgen heap settings currently?

      The default metaspace size settings in EAP 7 are:

      -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m

      Currently, the metaspace size values can be set by passing values via the JAVA_OPTS_APPEND environment variable.
