> 1) In TCTLSeparatedProtocol.SimpleTransportTokenizer.nextToken() is doing null check
for the tokenizer.
> If tokenizer is null, fillTokenizer() method is called to get the tokenizer object. But
fillTokenizer() method also can update the tokenizer with NULL , so NULL check should be done
before using the tokenizer.
> 2) Also improved some logging in TCTLSeparatedProtocol.java
