    Error while integrating modeshape 2.8.x with JGroups3.x

    Neil Zou Newbie

      I'm now using modeshape 2.8.2, we need to use modeshape cluster feature. JGroups-3.0.9 is already used in system, so we removed jgroups dependency while adding modeshape clusting jar:

       

      <dependency>
        <groupId>org.modeshape</groupId>
        <artifactId>modeshape-clustering</artifactId>
        <version>${modeshape.version}</version>
          <exclusions>
            <exclusion>
              <groupId>org.jgroups</groupId>
              <artifactId>jgroups</artifactId>
            </exclusion>
          </exclusions>
      </dependency>
      

      And I updated the jgroups configuration file as JGroups3 style, details attached.

       

      But while we starting application, got below error, does modeshape 2.8.X only support JGroups 2?

          I check modeshape source code again.

          Found below code, so I guess this issue can't be resolved by configuration change..

           

          import java.io.ByteArrayInputStream;
          import java.io.IOException;
          import java.io.InputStream;

            does modeshape 2.8.X only support JGroups 2?

            As you might have guessed, ModeShape 2.8 requires JGroups 2.10.0.GA. Not only have we not even tested other versions of JGroups 2, but as you noticed it probably won't even compile against JGroups 3 (major releases often entail an API change).
