             Summary: GetFTP NullPointerException on 1.1.1
                 Key: NIFI-3595
                 URL: https://issues.apache.org/jira/browse/NIFI-3595
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 1.1.1
         Environment: API version is 0.6.1 and deployed on 1.1.1
            Reporter: Mahfuzul Amin


GetFTP processor throws NullPointerException randomly on 1.1.1. Recently we have installed the version 1.1.1. We have another server where nifi version 0.6.1 is running. According to our observation GetFTP works fine on version 0.6.1. To replicate the flows we have copied the flow.xml.gz file from nifi 0.6.1 to 1.1.1.Our custom processors are using the API version 0.6.1 in the project. The stacktarce is given below:
