Description

When using Stateless NiFi, the TriggerResult has a readContent(FlowFile) method that should return the contents of the FlowFile. However, if a FlowFile was created using ProcessSession.clone(FlowFile flowFile, long offset, long size) then the contents of the entire content claim are still returned, not just the contents between offset & offset + size. This means that any stateless flow where the output is from SplitText or SegmentContent will return too much content.
