----------------------------------
Summary: JSON Convertion of streams can throw an NPE
Key: SLING-10425
URL: https://issues.apache.org/jira/browse/SLING-10425
Project: Sling
Issue Type: Bug
Reporter: Karl Pauls
The getLength() call for streams has been changed in

Long.class) - that can cause an NPE if there is no value for the key.
