jodd: Madvoc 3->4: Body is empty for `req.getReader()` as well ass `@In @Scope(BODY)`

Current behavior

Sorry, to nag again 😕

After porting an Madvoc application from v3.x to 4.x it cannot read any PUT Body content. The originally, ported form was:

       @Action("/list/{id}") @PUT
	public JsonResult updateList(@In("id") String id) {
            return GroceryService.get().updateGroceryList(id,  request.getReader());
	}

I modified it to this form which does not help:

        @Action("/list/{id}") @PUT
	public JsonResult updateList(@In("id") String id, @In @Scope(BODY) String listJson) {
            return GroceryService.get().updateGroceryList(id,  new StringReader(listJson));
	}

I’m a little bit lost and hope I do not miss anything. Tested it with two web servers to sort out the issue thre.

Expected behavior

request.getReader() and/or @In @Scope(BODY) String listJson should contain the actual request body text.

Steps to Reproduce the Problem

git clone --depth=3 --branch=master https://github.com/bentolor/microframeworks-showcase.git showcase
cd showcase
./gradlew :jodd:run

Then go to http://localhost:8080/, Click “Lists” in the left section, “Edit” in the List, Remove an item, press Save.

OR

Open Project with IDEA IntelliJ and Run “Jodd: Run Example”.

OR

./gradlew :jodd:jettyRun

to use Jetty instead of Undertow.

Any ideas what I’m missing?
