(stepfunctions): java sdk JsonPath.mapAt

[charlie-harvey]

Describe the feature

The java library is tougher to work with than Typescript (or other languages) because you can't just throw random json into the object and call it a day. You have to deal with the types, even though you don't want to. I want to pass a parameter into the BatchSubmitJob BatchContainerOverrides.environment. But I can't, because its a Map.

There is

Use Case

There are functions for dealing with string, numbers and lists, but no maps:

    JsonPath.stringAt(path);
    JsonPath.numberAt(path);
    JsonPath.listAt(path);

Proposed Solution

What I want:

    JsonPath.mapAt(path):

Other Information

There is a JsonPath.objectAt(path) function, but for the life of me I can't make it useful. It returns an IResolvable and I can't seem to turn that into anything. So it might as well not exist.
