Kafka - Issue with additionalProperties

[anandakrishnan ramakrishnan]

I am having issue with setting additionalProperties. I am setting the
property as below

    Map<String, String> additionalProperties = new HashMap<>();
            additionalProperties.put("sasl.login.callback.handler.class",

 "io.confluent.kafka.clients.plugins.auth.token.TokenUserLoginCallbackHandler");

Followed by the Kafka route builder is setup as below

    .additionalProperties(additionalProperties)

However the property i see populated in the kafka config show up as
"sasl"->"io.confluent.kafka.clients.plugins.auth.token.TokenUserLoginCallbackHandler"

The reason being the PropertyBindingSupport.java is splitting by dot

// we should only walk and create OGNL path for the middle graph

    String[] parts;
    if (isDotKey(name)) {
        parts = splitKey(name);
    } else {
        parts = new String[] { name };
    }

// which only picks up "sasl" instead of "sasl.login.callback-handler.class"

    newName = parts[i + 1];

Any help is appreciated.
