org.apache.ignite.IgniteCheckedException: Failed to find class with given class loader for unmarshalling -

using ignite 2.1, start first node in default server mode peer class loading enabled command line. see following line in logs:

when start second node (using ignitespringbean on tomcat server, in client mode) getting following error, though peer class loading enabled:

org.apache.ignite.ignitecheckedexception: failed find class given class loader unmarshalling (make sure same versions of classes available on nodes or enable peer-class-loading) [clsldr=sun.misc.launcher$appclassloader@18b4aac2,... 

visor tells me both server , client node in topology , both have peer class loading enabled...
