It's finally here, the next major release of Dropwizard! This one has been developed and released in tandem with Dropwizard 3.0.0.
If you're wondering what the differences are: Not much!
3️⃣ Dropwizard 3.0.0 is still based on and is using dependencies for Java EE and the javax.* package namespace. The effort to migrate from Dropwizard 2.x to Dropwizard 3.0.0 should be minimal for many projects.
4️⃣ Dropwizard 4.0.0 is based on and is using dependencies for Jakarta EE and the jakarta.* package namespace. The effort to migrate from Dropwizard 2.x to Dropwizard 4.0.0 might be bigger due to more package changes and more breaking changes in our dependencies.
📣 In any case, let us know how the migration went and if you were missing anything important in the upgrade notes in our GitHub Discussions!
Dropwizard 4.0.0 and later require Java 11 as a baseline. Later versions of Java are also working.
Dropwizard Package Structure and JPMS
In order to properly support the Java Platform Module System (JPMS), the Java packages in modules must not overlap, or put differently, the packages may not be split into multiple modules.
Dropwizard 4.0.0 won’t enable full support for the JPMS. Instead, as a transition step, automatic modules are introduced.
Affected packages:
Maven module
Old package
New package
dropwizard-core
io.dropwizard
io.drowizard.core
dropwizard-logging
io.dropwizard.logging
io.dropwizard.logging.common
dropwizard-metrics
io.dropwizard.metrics
io.dropwizard.metrics.common
dropwizard-views
io.dropwizard.views
io.dropwizard.views.common
Transition to Jakarta EE
Previously released Dropwizard versions used Java/Jakarta EE dependencies under the javax namespace. Dropwizard 4.0.x transitioned to Jakarta EE 9 components and therefore utilize the new jakarta namespace for many components.
This means that most of the imports of existing applications using Dropwizard 2.x or 3.x will have to be changed from the javax to the jakarta namespace. However, other components still use the javax namespace, so a simple search and replace could break other imports.
Jakarta EE 9 compatibility
As stated above, Dropwizard 4.0.x will transition to Jakarta EE 9 components. This means, Dropwizard will now try to be consistent with one specific EE version.
Therefore Dropwizard 4.0.x will stay on components of Jakarta EE 9 and the transition to components of Jakarta EE 10 will be postponed to an other release series.
Since the EE version bump will probably introduce breaking changes, the Jakarta EE 10 components will be most likely integrated in Dropwizard 5.0.x and not in a 4.1.x release.
