Hi All, It looks like the parent of tomcat bundle classloader has been system classloader in new kernel. Old kernel it is the OSGI Classloader. Due to this, the classes in Webapp can not see or load classes from the OSGI environment. But it works if the classes are loaded via OSGI bundle.
Two options exists, if the above is the case. 1. Make the tomcat classloader's parent as Equinox classloader. Not sure how to do this at the moment, to retain previous behavior on 4.4.x 2. Move the modules in "org.wso2.carbon.identity.user.api" as OSGI bundles.
