Hi Roman,
Thank you for reporting this! I looked into and on my machine I was
able to receive events on client-handler node but exception occurred
in the local listener! In a following line:
System.out.println("Received event [evt=" + evt.name() + ",
cacheName=" + evt.cacheName() + ", key=" + evt.key().toString());
This indeed looks like a weird bug. Event appears broken after
deserialization on a listener side after it is received from a server.
