Possible problem:

* N threads are trying to execute task.
* The first thread is trying to put registered class into marshaller cache (see {{MarshallerContextImpl.registerClassName}}). Performs put locally and waiting for responses from backups.
* The second thread get registered class locally (first thread already updated cache) and send task to remote node.
* Remote node (it is backup node) trying to deserialize task and get class descriptor by {{typeId}}. But update from first thread still is not executed on this node. Task execution fails because can't deserialize task.
