> Components: ipc
> Affects Versions: 2.7.1

> If there's any problem in the constructor of {{SaslRpcClient}}, then IPC
> Client throws an NPE rather than forwarding the stack trace. This is because
> the exception handler assumes that {{saslRpcClient}} is not null, that the
> exception is related to the SASL setup itself.
> The exception handler needs to check for {{saslRpcClient}} being null, and if
> so, rethrow the exception
