bad or not json output via rest call to layergroup

Description

2 grouped layers (VECTEUR and AUTOROUTE) are created with many layers (not the same set of layer)
each layer has its own SLD style assigned
all layers can be previewed properly

The call to http://carto-geoserver:8080/geoserver/rest/workspaces/SDIS/layergroups/VECTEUR.json returns nothing and we get this exception in geoserver logs:

The call to http://carto-geoserver:8080/geoserver/rest/workspaces/SDIS/layergroups/VECTEUR.xml returns good data (see vecteur.xml file).

The call to http://carto-geoserver:8080/geoserver/rest/workspaces/SDIS/layergroups/AUTOROUTES.json returns strange data in styles tag (see AUTOROUTES.json file).

And here is the xml version (see AUTOROUTES.xml file).

Is this a known bug, as I not found something equivalent? Is there a workaround?

Thanks,
regards,
Rot Ulet.

Similar problem occurs in rest/monitor/requests/, when requesting json representation for request. Bug occurs in requests where RequestData contains bbox element. XML response will contain correct dataset, while json representation will return empty response with 200 OK status. For example:

this works fine (samples taken from http://demo.geo-solutions.it/geoserver/rest/monitor/requests/):

xml:

Going to guess this is a deep xstream xml --> json conversion bug.

The original has a bunch of empty style tags:

<styles>
    <style/>
    <style/>
    <style/>
...
    <style/>
  </styles>

For reference the strange output is:

"style":[
      "",
      "",
      {
         "style":[
            "",
