Hi Sameera/All,
We've been trying to find the cause for this issue without much success. It
seems this issue [1] is a bit strange. The reason is that this is
intermittent. Even though tomcat bundle (which tries to load the said from
o.w.c.tomcat.ext bundle) has the DynamicImport-Package set to '*', it fails
to load that class org.wso2.carbon.tomcat.ext.servlet.DelegationServlet
intermittently. After this error, the server start-up hangs.
This is some sort of intermittent osgi wiring issue as I understand. The
error occurs during the deployment of the carbon webapp where the
DelegationServlet is a servlet defined in its web.xml. We have recently,
included some tomcat classes in the o.w.c.tomcat.patch which is a
Require-Bundle of the tomcat bundle (via the o.w.c.tomcat.fragment.dummy
fragment bundle). It exposes the following packages. [2] I don't see any
correlation between this change and the error, but this change might have
caused the issue. It's not easy to verify this since the issue is less
frequent.
We are at a loss identifying any potential issues here. Any suggestions are
welcome.
