[jira] [Commented] (NIFI-8496) NiFi returns 500 error when uploading templates

["Mark Bean (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-8496?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17338384#comment-17338384 ] 

Mark Bean commented on NIFI-8496:
---------------------------------

Ultimately, I believe this issue is caused by the fact that jersey-media-jaxb is no longer a dependency in jersey-server (2.33) - it is now scoped to 'test'. Therefore, we must include it explicitly where needed.

I was able to eliminate the 500 error by adding the following to:
nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-web/nifi-jetty/pom.xml

        <dependency>
            <groupId>org.glassfish.jersey.media</groupId>
            <artifactId>jersey-media-jaxb</artifactId>
            <version>${jersey.version}</version>
        </dependency>

My question is whether that is too "low level"? Are there modules other than nifi-jetty which may need this. The code compiles file, but I'm worried about more runtime behavior problems.

Thoughts?
