How to Run the Security Server Using Java 11?

Starting with X-Road 6.26.0, it is possible to run the X-Road Security Server using Java version 11. However, Java 11 support is still experimental and not recommended for production environments.

To install and configure Java 11 on the Security Server version 6.26, please follow the steps below.

• Install OpenJDK 11 runtime environment

  Ubuntu

  sudo apt install  openjdk-11-jre-headless

  RHEL

  sudo yum install java-11-openjdk-headless

• Modify /etc/xroad/services/local.conf so that JAVA_HOME points to the Java 11 runtime and add a system property to disable a legacy optimization that does not work on Java version 11.

  Ubuntu

  JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
  XROAD_PARAMS="$XROAD_PARAMS -Dcom.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize=true "

  RHEL

  JAVA_HOME=/usr/lib/jvm/jre-11-openjdk
  XROAD_PARAMS="$XROAD_PARAMS -Dcom.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize=true "

• Restart X-Road services

  sudo systemctl restart "xroad-*"
