Please provide a summary of the update, including the following points:

• A sentence or two that introduces the update to someone new to the general technology/concept.
  Open Liberty InstantOn provides fast startup times for MicroProfile and Jakarta EE applications. InstantOn supports a subset of Open Liberty features. As of the 25.0.0.4 release, the following features are enhanced to support InstantOn.

• The Human-readable name and short feature name for your feature- eg WebSockets feature (websockets-1.0).

        J2EE Management 1.1 (j2eeManagement-1.1)
        Application Client Support for Server 1.0 (appClientSupport-1.0)
        Jakarta Application Client Support for Server 2.0 (appClientSupport-2.0)
        Web Service Security 1.1 (wsSecurity-1.1)

• Who is the target persona? Who do you expect to use the update? eg application developer, operations.

  Application developer and operations

• What was the problem before and how does your update make their life better? (Why should they care?)

  InstantOn supports a subset of Open Liberty features. Any public features that are enabled outside of the supported set of features for InstantOn cause the checkpoint to fail with an error message. Starting with the 25.0.04 release, the newly supported features include J2EE Management 1.1 (j2eeManagement-1.1), Application Client Support for Server 1.0 (appClientSupport-1.0), Jakarta Application Client Support for Server 2.0 (appClientSupport-2.0) and Web Service Security 1.1 (wsSecurity-1.1)

• Briefly explain how to make your update work. Include screenshots, diagrams, and/or code snippets, and provide a server.xml snippet.

A Liberty InstantOn checkpoint and restore can now be performed with a Liberty server configured with the features that have been enhanced for InstantOn support.

• Where can they find out more about this specific update (eg Open Liberty docs, Javadoc) and/or the wider technology?

What happens next?

• Add the label for the GA you're targeting: target:YY00X.
