Amelchev Nikita commented on IGNITE-4284:
-----------------------------------------
I try to do p2p class loading for discover. At now handlers with filters
connecting node's register before node state=connected. But unmarshal this
filtres is being done by optimized marshaller and its need sys-marshaller cache
that loaded after state=connected. Some attempts to register handlers after
start sys-cache lead spontaneous errors deserialize object by classloader (I
used p2p code from start query) and crash some test with backups or reconnect
nodes. I try to resolve it.
