RE: java.lang.IncompatibleClassChangeError: Implementing class

[Matthieu Cormier]

Hello Jean-Baptiste,

I'm using Java 1.6.  I just tracked the error down to ${servicemix-version} in 
the pom.xml for the JMS SU.  Setting the version to a valid number fixed the 
issue.

Thanks,

     <groupId>org.apache.servicemix.tooling</groupId>
     <artifactId>jbi-maven-plugin</artifactId>
     <version>${servicemix-version}</version>
     <extensions>true</extensions>
     <configuration>
       <type>service-unit</type>
     </configuration>
   </plugin>
 </plugins>

Hi Matthieu,

Which JVM version do you use ?
