Description
async-http-client currently depends on com.sun.activation:jakarta.activation:2.0.1 (compile scope, declared in the root pom.xml).
This artifact is no longer maintained. As part of decoupling the Jakarta Activation API from its implementation, development of the implementation moved to the Eclipse Angus project: https://eclipse-ee4j.github.io/angus-activation/. The old combined API+implementation artifact com.sun.activation:jakarta.activation saw its last release (2.0.1) in 2021 and will not receive further updates.
Current usage
The dependency is used in exactly one place: org.asynchttpclient.request.body.multipart.FileLikePart uses jakarta.activation.MimetypesFileTypeMap to resolve a content type from a file name, backed by the bundled ahc-mime.types resource.
Option A — migrate to the maintained artifacts
Replace the single dependency with the split API + implementation:
<dependency>
<groupId>jakarta.activation</groupId>
<artifactId>jakarta.activation-api</artifactId>
<version>2.1.3</version>
</dependency>
<dependency>
<groupId>org.eclipse.angus</groupId>
<artifactId>angus-activation</artifactId>
<version>2.0.2</version>
<scope>runtime</scope>
</dependency>No source changes are needed: MimetypesFileTypeMap keeps the jakarta.activation package. The runtime implementation is required because in Jakarta Activation 2.1+ the mime-type registry parsing is provided via ServiceLoader by the implementation.
Option B — eliminate the dependency entirely (preferred?)
Since the usage is limited to a simple "file extension → content type" lookup over AHC's own ahc-mime.types file, the dependency could be removed by replacing MimetypesFileTypeMap with a small internal parser/map. This would remove a compile-scope dependency from the classpath of all downstream consumers and avoid Jakarta Activation version conflicts in applications that also use Jakarta Mail/EE.
Related: #1589 previously raised the desire to avoid this dependency.
