Description

There does not seem to be an option currently to ignore the null property values in the odata json response. 

For example, we would like to have:

{ "name": "abc", "description": null}

returned as:

{ "name": "abc"}

 

ASP.Net currently has this feature: https://stackoverflow.com/questions/14486667/suppress-properties-with-null-value-on-asp-net-web-api

I believe this would require enhancements to https://github.com/apache/olingo-odata2/blob/ae1653b2fbd1ac579ea7dfaec46af6dd150aa743/odata2-lib/odata-core/src/main/java/org/apache/olingo/odata2/core/ep/producer/JsonEntryEntityProducer.java
