ExchangeStrategies custom codec's reader and writer are not registered

See original GitHub issue

Affects: 5.2.6.RELEASE

I added my custom encoder and decoder like following.

ExchangeStrategies
    .empty()
    .codecs(configurer -> {
        configurer.defaultCodecs().maxInMemorySize(properties.getMaxInMemorySize());
        configurer.customCodecs().registerWithDefaultConfig(encoder);
        configurer.customCodecs().registerWithDefaultConfig(decoder);
    })
    .build();

But there is no messageWriters when writing body with BodyInserts.fromValue(). It seems that encoder and decoder that I added above are not registered at ExchangeStrategies.

I think following code block has bug. Why put all readers and writers from this to other? It seems that this and other are swapped.

If it is a bug, I would like to create a PR. 😃

Yes, that looks like a bug.

Feel free to submit a PR with the fix, and please make sure to include a test that fails before the fix and passes afterwards.
