> 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
