Response element (<response>) causes StackOverflow when used above Apikit router

[SlightlyDave]

Hi,

When running the migrator for a project that contains elements which are placed in the entry point into the API just before the apikit element causes a java.lang.StackOverflowError, removing these tags from the source API allows the migration tool to complete correctly.

The command line that was used:

java -jar mule-migration-assistant-runner-1.1.0.jar -projectBasePath C:\MuleSoft\Mule3to4Projects\Mule3Api -parentDomainBasePath C:\MuleSoft\Mule3to4Projects\Mule3Domain -muleVersion 4.3.0 -destinationProjectBasePath C:\MuleSoft\Mule4Projects\Mule4Api

Example Code:

`

    <http:listener config-ref="Ref" path="${api.http.listener.path}" doc:name="HTTP" >
    </http:listener>

    <set-property propertyName="vTimeStamp" value="#[server.dateTime.format('YYYY-MM-dd HH:mm:ss,S')]" doc:name="Set TimeStamp"/>
    
	<response>
		<set-property propertyName="vTimeStamp" value="#[server.dateTime.format('YYYY-MM-dd HH:mm:ss,S')]" doc:name="Set TimeStamp"/>
	</response>


    <apikit:router config-ref="api-config" doc:name="APIkit Router" />
    <exception-strategy ref="global-exception-strategy" doc:name="Reference Exception Strategy" />
</flow>`

Command output:

Executing migrator 1.1.0... Exception in thread "main" java.lang.StackOverflowError at org.jdom2.Content.getDocument(Content.java:231) at org.jdom2.Content.getDocument(Content.java:231) at com.mulesoft.tools.migration.step.util.XmlDslUtils.isTopLevelElement(XmlDslUtils.java:501) at com.mulesoft.tools.migration.library.apikit.steps.ApikitHttpListenerMapping.getParentFlow(ApikitHttpListenerMapping.java:95) at com.mulesoft.tools.migration.library.apikit.steps.ApikitHttpListenerMapping.getParentFlow(ApikitHttpListenerMapping.java:103) at com.mulesoft.tools.migration.library.apikit.steps.ApikitHttpListenerMapping.getParentFlow(ApikitHttpListenerMapping.java:103)

Hi @SlightlyDave the example code seems to be broken.
Can you please try to isolate the issue in a simple Mule 3 app and add the example to the issue so that it can be reproduced?

Thanks, @holiday-sunrise! The app is consistent with what we observed. We will review your pull request soon.
