Sling servlet invalid recursion selector with json extension

I am registering a Sling Servlet using

@Component(service=Servlet.class,
           property={
                   Constants.SERVICE_DESCRIPTION + "=Simple Demo Servlet",
                   "sling.servlet.methods=" + HttpConstants.METHOD_GET,
                   "sling.servlet.resourceTypes="+ "myapp/components/structure/page",
                   "sling.servlet.extensions=" + "json",
                   "sling.servlet.selectors=" + "myselector"
 })

But when calling URL <host:port>/content/myapp/en.myselector.js I get error

Invalid recursion selector value 'myselector'
Cannot serve request to /content/myapp/en.myselector.json in 
org.apache.sling.servlets.get.DefaultGetServlet

If we remove "sling.servlet.extensions=" + "json", from annotation, we are able to hit the servlet using <host:port>/content/myapp/en.myselector.js or <host:port>/content/myapp/en.myselector.html but not <host:port>/content/myapp/en.myselector.json

Any additional configurations required? or its conflicting with DefaultGetServlet? We were trying to expose JSON out of resource using servlet and JSON extension semantically making sense.

Since you've registered the servlet against the resource instead of a path, the resource is actually the jcr:content node of the page, rather than the page node itself.

Hence, the servlet should work when accessed with the jcr:content in the URL as shown below

<host:port>/content/myapp/en/_jcr_content.myselector.json
