Hi,

some days ago I have opened a JIRA in order to report a problem in GeoServer.

I have found a bug in GeoServer REST request to get coverages metadata in json format.

If I send the following request:

http://localhost:8080/geoserver/rest/workspaces/nurc/coveragestores/mosaic/coverages/mosaic.json

GeoServer produces an exception as the following:

... and the .json file results empty.

I think that this problem can depend on the presence of NaN values.
