Hi Jeffrey, The slf4j 1.5.10.wso2v1 jar seems to be coming from the core carbon kernel components. Therefore, its not possible to remove it from the build. Since you have mentioned that manually removing it resolved the issue, you can exclude it from the cartridge agent build and test if the issue is resolved. To do this, please add an exclusion condition to [1], in the dependencySets element in your local build. There are some existing exclusions that you can refer to.
