Hi all,
I'm finding intermittent class-loading issue, when accessing a class where
it bundled in dss from a web-app. I'm using Carbon Environment in my web
app class-loading.xml.
Please find the below ClassNotFound Exception below.

When I start the server in osgi console, I found that the tomcat doesn't
see the package, I have exported package correctly.
osgi> p org.wso2.carbon.dataservices.core
org.wso2.carbon.dataservices.core;
version="4.3.1.SNAPSHOT"<org.wso2.carbon.dataservices.core_4.3.1.SNAPSHOT
[145]>
org.wso2.carbon.dataservices.task_4.3.1.SNAPSHOT [149] imports
osgi>
Any help on this matter is highly appreciated.
Thanks,
Madhawa
