I'm trying to create a test case for my Jersey REST application.
I added already in pom.xml:
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.25</version>
</dependency>
I'm creating my client with:
Client client = ClientBuilder.newBuilder()
.register(MoxyJsonFeature.class)
.register(MultiPartFeature.class)
.build();
But this is failing with an InstantiationException on line .register(MultiPartFeature.class). Here is the full stack trace:

I don't understand what I'm missing here. I followed Jersey documentation but I might have missed something.
When I remove the line .register(MultiPartFeature.class), I'm able to run REST tests normally using my client.
Any idea?
The problem was caused by another dependency in my project: org.apache.tika:tika-langdetect:1.14. tika-langdetect adds apache CXF to the classpath which seems to trouble a bit Jersey.
When excluding CXF from my project, I can see that Jersey is only using "Jersey" classes:

I now need to understand why actually this CXF dependency is confusing Jersey but that's another story :)
EDIT: basically you can't have both CXF and Jersey on the same classpath as they are providing different implementation for the same JaxRS feature.
For my project, I don't need Tika upload/download features, so I can simply exclude Apache CXF from tika dependencies with:
<dependency>
<groupId>org.apache.tika</groupId>
<artifactId>tika-parsers</artifactId>
<version>1.14</version>
<exclusions>
<exclusion>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-rs-client</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.apache.tika</groupId>
<artifactId>tika-langdetect</artifactId>
<version>1.14</version>
<exclusions>
<exclusion>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-rs-client</artifactId>
</exclusion>
</exclusions>
</dependency>
