I’ve uploaded a video in which I show how to reduce the turnaround times while writing Enterprise Java applications that are deployed on Open Liberty.
The liberty:dev goal of the Maven plugin watches for file changes and applies the changes instantly, without the need to rebuild the whole deployment artifact.

When using CDI with asynchronous execution methods, such as a ManagedExecutorService, it’s traditionally not possible to access all of CDI’s scopes that were active in the originating thread.
MicroProfile Context Propagation enables to define and pass thread execution contexts to completion stages where our code can access various CDI contexts despite being executed asynchronously.
Additionally, Context Propagation allows to create managed executor services, that can be injected and used inside our beans, for example to realize bulkheads.

When you’re testing your enterprise application in a Kubernetes environment, the turnaround for changing, re-packaging, and re-deploying your application can become quite high.
Telepresence aims to mitigate this, by proxying a locally running process into our Kubernetes cluster, as if the local process were part of the cluster.
If we combine that approach with a hot-redeploy tool such as WAD we can vastly improve our development productivity.

The Eclipse Foundation announced that Jakarta EE cannot continue to use the javax package name.
Apparently this comes with the fact that while Java EE bases on this name, no further modifications are allowed to classes or packages starting with that name.
