What Jersey version do I need to download for JDK 1.9?

Question

I am using jdk 1.9. I am trying to bring up a simple ReST service. Created the project using the maven archetype: jersey-quickstart-webapp. Then I went ahead and modified the pom.xml and web.xml. My maven config is as shown below:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

When I change the build configuration from 1.9 to 1.8

<configuration>
    <source>1.8</source>
    <target>1.8</target>
</configuration>

the service comes up without any issues and I see the expected result on the browser.

I am using Intellij, Project SDK - 9, Project Language Level - 9

What jars should I import in order to make it work with 1.9 ? Or do I need to change maven configuration to make it work ?

Answer 1

The problem that current Jersey has a shaded asm 5 dependency, which doesn't work with Java 9 bytecode. Looks like Jersey 1.x is not adopted to Java 9 and it's unclear if this support is coming at all. As a temporary solution, I made a branch where I deleted shaded asm, migrated packages in code to use a regular asm dependency and put asm 6.0 in maven dependencies.

You can build only jersey-server and jersey-servlet modules from this branch because only these two depend on asm and use these two custom artifacts in your project.

My projects work fine with such a replacement, but I can't guarantee that it's 100% working solution, I wasn't able to build the whole distribution without fails and can't invest time for a full adoption and check right now. On the same time, the main Jersey parts built without issues.

So, your final pom would look like:

<!--regular jersey dependencies with the last 1.19.4 version-->
<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-server</artifactId>
    <version>${custom-jersey-with-asm6.version}</version>
</dependency>

<dependency>
     <groupId>com.sun.jersey</groupId>
     <artifactId>jersey-servlet</artifactId>
     <version>${custom-jersey-with-asm6.version}</version>
</dependency>

<dependency>
     <groupId>org.ow2.asm</groupId>
     <artifactId>asm</artifactId>
     <version>6.0</version>
</dependency>

Answer 2

There are quite a few artifacts that you might need to update. To start with you shall check your module's mvn dependency:tree to look out for any source of asm that brings in version < 6.0.x since that is not compatible with Java9. From the current pom.xml and as inferred from your execution logs, you can update

<!-- https://mvnrepository.com/artifact/asm/asm -->
<dependency>
    <groupId>asm</groupId>
    <artifactId>asm</artifactId>
    <version>3.3.1</version>
</dependency>

to

<dependency>
    <groupId>org.ow2.asm</groupId>
    <artifactId>asm</artifactId>
    <version>6.0</version>
</dependency>

---

Importantly, use Java 9 compatible maven plugins such as -

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.7.0</version>
    <inherited>true</inherited>
    <configuration>
        <source>9</source>
        <target>9</target>
    </configuration>
</plugin>

---

On a side note, you might end up still facing some other challenges(I can see conflicting jaxb dependencies, even asm might be transitive from jersey) to resolve which you shall run

mvn dependency:analyze

and make sure that conflicting dependencies are excluded in such cases to make use of their updated version.
