ClassNotFoundException during start but working?!

[Philipp Meyer]

Hello out there,

i'm wondering why am i getting the following error in the console when i start my plugin via atlas-package, but everything is working fine though when the plugin is running.  I'm trying to get rid of this error in the console but can't find the problem. 

The Error:

My plugin.xml

<component key="tx-processor" name="Transactional Annotation Processor"
         class="com.atlassian.activeobjects.external.TransactionalAnnotationProcessor">
   <description>Processes @Transactional annotations.</description>
</component>

<!-- used this compnent import; replaced it with @Component in the class itself. 
 <component key="field-definition-service" name="Field Definition Service" class="de.mycompany.confluence.service.FieldDefinitionServiceImpl"/> -->

The interface:

package de.mycompany.confluence.service;

import com.atlassian.activeobjects.tx.Transactional;

@Transactional
public interface FieldDefinitionService {
            // some methods to implement
}

 The implementation:

package de.mycompany.confluence.service;

import com.atlassian.activeobjects.external.ActiveObjects;


// Imported all of those to test some different annotations...
import com.atlassian.plugin.spring.scanner.annotation.component.Scanned;
import com.atlassian.plugin.spring.scanner.annotation.imports.ComponentImport;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;


@Scanned
@Component
public class FieldDefinitionServiceImpl implements FieldDefinitionService {

    private final static Logger LOGGER = LoggerFactory.getLogger(FieldDefinitionServiceImpl.class);

    private final ActiveObjects ao;

    @Autowired
    public FieldDefinitionServiceImpl(@ComponentImport final ActiveObjects ao) {
        this.ao = checkNotNull(ao, "Active Objects Null @FieldDefinitionServiceImpl constructor");
    }

    
    // Method implementations...

I don't get where the actual problem is here.. maybe someone can help?

Thanks in advance!
