We are running into the following problem:
. we start Tomcat in an embedded manner:
use a server.xml that only includes interceptors and connectors
create contexts programmatically
initialize the context manager
I am observing the following behavior:
the tomcat is making the ports available before the context finished
being initialized.
On trying to access the application at that time, we get the following
java.lang.NoClassDefFoundError: com/sun/esm/web/server/ServerUtils
at com.sun.esm.web.servlet.CMCServlet.service(CMCServlet.java:354)

From that moment on, we are never able to access the webserver, getting
the same message again and again.

It appears that there is a race condition on the ContextManager.start()
method.
I instrumented my context manager startup to print when the return
from ContextManager.start occurs.
I try to access my initial page (which is actually a servlet)
repeatedly from a browser trying to catch the point in time where
the connector is made available by the contexts are not.
When I manage to access the port on the connector
the result is the above exception.
Does anybody else see something similar ?
