There is a poller, ONE default POLLER, but compiler is throwing an error that my context contains more than one poller. How it's possible? I think so it's some kind of bug.
Help me please, if someone met it.

Answer 1

According to your StackTrace it looks like you load META-INF/spring/applicationContextMail.xml twice.
Typically that happens when you import it within dispatcherServlet initialization and as regular one through the ContextLoaderListener.
Be sure that you <import> your config only once.
