Invalid Auth config file when using credsStore #806
Description
Using a "credsStore" configuration for auth in ~/.docker/config.json causes AuthConfigFile to fail with an IOException.

After a little debugging it looks like the json parsing fails silently a little earlier in AuthConfigFile.java:
com.fasterxml.jackson.databind.JsonMappingException: Can not instantiate value of type [map type; class java.util.LinkedHashMap, [simple type, class java.lang.String] -> [simple type, class com.github.dockerjava.api.model.AuthConfig]] from String value ('osxkeychain'); no single-String constructor/factory method
