> org.apache.openejb.core.mdb.MdbInstanceFactory class pass invalid 
> ThreadContext instance to ThreadContext.exit method at line 263 of its 
> constructBean method. This brokes stack-like usage of ThreadContext objects 
> and leads to problems during lazy initialization of ejb components when they 
> called for the first time from the web tier. In particular ClassCastException 
> is thrown in 
> org.apache.geronimo.tomcat.interceptor.InstanceContextBeforeAfter.before() at 
> line 49, because ConnectorInstanceContextImpl instance is returned instead of 
> SharedConnectorInstanceContext instance. This error results in that 
> org.apache.geronimo.tomcat.listener.DispatchListener.beforeDispatch method 
> does not put any data into the current context stack so when the 
> afterDispatch method is called the current context stack throws 
> java.util.EmptyStackException.
