QuickFixJ session 配置为 null。SessionSettings InputStream InputStreamReader TokenizerToken 生成 null

Question

In QuickFixJ the config file is not read, causing session settings to be null, but the initiator still starts, but doesn't connect anywhere. There are no log or store directories produced and no error given.

Using the normal config file loading process set out in the docs, the config file is read under the hood by the SessionSettings.java class. It uses the following code:

private void load(InputStream inputStream) throws ConfigError {
    try { 
        Properties currentSection = null;
        String currentSectionId = null;
        final Tokenizer tokenizer = new Tokenizer();
        final Reader reader = new InputStreamReader(inputStream);
        Tokenizer.Token token = tokenizer.getToken(reader);
        while (token != null) {
        ...

This is my inputStream

It looks like a good inputStream but the tokenizer is consistently producing null .

There's nothing wrong with the QuickFix config file FIX.cfg that I can see. I am using JDK11.

Answer 1

The issue was that my config file was saved with Character Encoding UTF-8 with BOM by Notepad which was very unexpected.
