JRE version selection

Prior to Java 9, developers could request a JRE version other than the version being launched when launching an application. This could be accomplished with a command-line option or with a proper JAR file manifest configuration. This feature has been removed in JDK 9 because of the way we typically deploy applications. Here are the three primary methods:

  • Active installers
  • Java Web Start using JNLP
  • Native OS packaging systems
