Description

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
