Hi Devs, Just wanted to follow up on this issue. We've confirmed that removing apache-stratos-cartridge-agent-4.0.0/lib/slf4j-1.5.10.wso2v1.jar fixed this issue. We're trying to see where this dependency is configured. I found the references to slf4j in [1], [2], and [3] in our code base. I assume [1] and [2] are auto-generated during maven build.
Any idea which config file controls contents of [1] and [2]? I also see that Stratos CLI code uses slf4j version 1.7.6 while cloud controller, load balancer and the rest uses version 1.6.4. Should we try to ensure all Stratos components references the same version of sl4j? If so, how? 1/- products/stratos/modules/p2-profile-gen/target/wso2carbon-core-4.2.0/repository/components/default/configuration/org.eclipse.equinox.simpleconfigurator/bundles.info slf4j,1.5.10.wso2v1,../plugins/slf4j_1.5.10.wso2v1.jar,4,true 2/- components/org.apache.stratos.cartridge.agent/target/maven-shared-archive-resources/META-INF/DEPENDENCIES - slf4j.wso2 (http://wso2.org) slf4j.wso2:slf4j:bundle:1.5.10.wso2v1 3/- components/org.apache.stratos.cartridge.agent/pom.xml <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.5</version> </dependency> Thanks, -Jeffrey From: "Martin Eppel (meppel)" <mep...@cisco.com<mailto:mep...@cisco.com>> Reply-To: "dev@stratos.apache.org<mailto:dev@stratos.apache.org>" <dev@stratos.apache.org<mailto:dev@stratos.apache.org>> Date: Sunday, July 13, 2014 12:03 PM To: "dev@stratos.apache.org<mailto:dev@stratos.apache.org>" <dev@stratos.apache.org<mailto:dev@stratos.apache.org>> Cc: "d...@stratos.incubator.apache.org<mailto:d...@stratos.incubator.apache.org>" <d...@stratos.incubator.apache.org<mailto:d...@stratos.incubator.apache.org>> Subject: RE: cartridge agent startup error (4.0.0 based source, local build) We merged our local changes which (were working and based on rc4), with 4.0.0 and now we are seeing this issue. Did we change library versions (used by cartridge agent) between rc4 and 4.0.0 ? Which pom files define all the cartridge agent dependencies ?

There are different versions of API and Integration libraries. Do you have any local changes? If so, please check in those classes if there are any imports related to a different version of SL4J.
