> Key: NIFI-2310
> URL: https://issues.apache.org/jira/browse/NIFI-2310
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.0.0
> Reporter: Yolanda M. Davis
> Assignee: Yolanda M. Davis
> Fix For: 1.0.0
>
>
> The following jolt spec failed to pass the validation check in
> JoltTransformJSON:
> {
> "\\@context": {
> "name": "&1.Name",
> "ingredient": "&1.Inputs",
> "yield": "\\@context.Makes",
> "*": "&1.&"
> },
> "name": "Name",
> "ingredient": "Inputs",
> "yield": "Makes",
> "*": "&"
> }
> The reason is the double backslash to escape '@' which should be supported to
> identify literal characters.
> Upgrading to Jolt version 0.0.21 should resolve this problem since it was
> fixed in that release.
