ANTLR NoClassDefFoundError error #176

Open jmacauley opened 7 years ago

Spent a couple days debugging this problem. I finally figured out what was wrong. I am using Apache Karaf (4.0.6).

Here is the error log:

This log would only show up when invoking a POST operation on a JAX-RS annotated method using the jax-rs-provider-moxy feature when a @XmlRootElement annotated class was referenced as a body parameter in the method parameters. The POST would fail. GET operations were fine. It would not occur using the jax-rs-provider-gson feature, or if I took care if the processing using an InputStream for the body parameter.

Here is a code segment:

@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
@Path("/models/{id}/deltas")
public Response propagateModelDelta(@PathParam("id") String id, DeltaRequest deltaRequest);

I determined that the EclipseLink ANTLR bundle was not loaded in my Karaf instance. If I look at the jax-rs-provider-moxy feature definition I see the EclipseLink Core is specified as a bundle dependency. 

<feature name="jax-rs-provider-moxy" version="2.2">
    <bundle dependency="true">mvn:org.eclipse.persistence/org.eclipse.persistence.core/2.5.2</bundle>
    <bundle dependency="true">mvn:org.eclipse.persistence/org.eclipse.persistence.moxy/2.5.2</bundle>
    <bundle>mvn:com.eclipsesource.jaxrs/provider-moxy/2.2</bundle>
</feature>

When I look at the EclipseLink Core 2.5.2.v20140319-9ad6abd bundle manifest it specified ANTLR at optional:

Require-Bundle: org.eclipse.persistence.antlr; bundle-version="3.2.0"; resolution:=optional

Which is allowing the bundle to load without the ANTLR bundle. Since Karaf does not have the ANTLR bundle loaded as a dependency it fails to find the targeted class.

I added the following dependency in my feature to force it to be loaded (not sure which ANTLR version I should be using).

<bundle  dependency="true">mvn:org.eclipse.persistence/org.eclipse.persistence.antlr/2.6.4</bundle>

This allowed me to clear the issue and use the jax-rs-provider-moxy feature.

I assume the solution is to specify this dependency in the jax-rs-provider-moxy feature definition like so?

<feature name="jax-rs-provider-moxy" version="2.2">
    <bundle dependency="true">mvn:org.eclipse.persistence/org.eclipse.persistence.antlr/2.6.4</bundle>
    <bundle dependency="true">mvn:org.eclipse.persistence/org.eclipse.persistence.core/2.5.2</bundle>
    <bundle dependency="true">mvn:org.eclipse.persistence/org.eclipse.persistence.moxy/2.5.2</bundle>
    <bundle>mvn:com.eclipsesource.jaxrs/provider-moxy/2.2</bundle>
</feature>

Thank you, John
