Josef Cacek updated JCLOUDS-1044:
---------------------------------
Environment: (was: Docker version: 1.9.1)
Labels: (was: docker)
Description:
JSON deserialization fails for {{null}} values in "inner collections/maps".
The adapters in {{NullFilteringTypeAdapterFactories}} are missing check for
*{{JsonToken.NULL}}*
Sample Java type, which can hit the problem:
{code}
Map<String, List<Map<String, String>>>
{code}
and JSON to reproduce the issue:
{code}
{"value":[null]}
{code}
or another one:
{code}
{"value":null}
{code}
The stacktrace then can look like:
{code}
