Is there a way to send Payload in HTTP Delete in WSO2 EI v6.4

Question

I am currently trying to access any REST service for deleting a resource from my WSO2 EI sequence. The code looks something like below

<?xml version="1.0" encoding="UTF-8"?>
<sequence name="DELETE_COMPANY_INFO" trace="disable" xmlns="http://ws.apache.org/ns/synapse">
    <log level="custom">
        <property name="Sequence" value="DELETE COMPANY INFO started"/>
    </log>
    <log level="custom">
        <property expression="json-eval($)" name="Request Payload"/>
    </log>
    <property name="NO_ENTITY_BODY" action="set" value="false" type="BOOLEAN" scope="axis2"/>
    <call blocking="true">
        <endpoint>
            <http method="delete" uri-template="http://<IP>:<Port>/companyinfo/<id>">
           </http>
        </endpoint>
    </call>
</sequence>

As can be seen I wish to send the message payload to this endpoint. However I am not able to send this as the payload is dropped by WSO2 EI v6.4 Logs are below

I know that REST Webservice implementation should not use Payload for HTTP DELETE operation, however I think ESB should not make the decision to drop the Payload if the underlying transport allows it. Additionally, I know that this issue was reported earlier (https://wso2.org/jira/browse/ESBJAVA-5060) and marked as resolved in v6.2 of WSO2 EI. However I am facing this in 6.4 version of EI.

Is there a solution to allow Payload with HTTP DELETE call using Call Mediator in WSO2 EI v6.4?

It seems the fix has gone to the Passthrough transport (non blocking) and not to the blocking transport. If you remove the blocking="true" mode, it should work.
