While debuging I see that
httpUpgradeHandlerClass in upgrade of org.apache.catalina.connector.Request
is
class org.apache.tomcat.websocket.server.WsHttpUpgradeHandler
InstanceManager is org.apache.catalina.core.DefaultInstanceManager
in the source code of my maven dependency of tomcat-api-7.0.47 this method
should exist:
public interface InstanceManager {
public Object newInstance(Class<?> clazz)
throws IllegalAccessException, InvocationTargetException,
NamingException,
InstantiationException;
...
Any clue ?
