INFRA-438 Handle observers not having error handling (#6434) 
* INFRA-438 Handle observers not having error handling

When the RPC client connection is closed, it notifies observers using onError(), which may not be the correct approach (TBD) but changing this is a much more invasive change. Where observers do not subscribe to error notifications, this is reflected to the calling client by an exception thrown.

This change catches that exception and lots it as debug rather an error level.

Corda is an open source blockchain project, designed for business from the start. Only Corda allows you to build interoperable blockchain networks that transact in strict privacy. Corda's smart contract technology allows businesses to transact directly, with value.

Features

  • Smart contracts that can be written in Java and other JVM languages
  • Flow framework to manage communication and negotiation between participants
  • Peer-to-peer network of nodes
  • "Notary" infrastructure to validate uniqueness and sequencing of transactions without global broadcast
  • Enables the development and deployment of distributed apps called CorDapps
  • Written in Kotlin, targeting the JVM

Getting started

  1. Read the Getting Started documentation
  2. Run the Example CorDapp
  3. Read about Corda's Key Concepts
  4. Follow the Hello, World! tutorial
