---------------------------------

             Summary: TLS toolkit throws NPE when accessed from root level
                 Key: NIFI-3319
                 URL: https://issues.apache.org/jira/browse/NIFI-3319
             Project: Apache NiFi
          Issue Type: Bug
          Components: Tools and Build
    Affects Versions: 1.1.1
            Reporter: Aldrin Piri


If accessing the TLS toolkit from a root level ( '/' on those using the *.sh 
tooling, presumably the same would occur in *.bat envs), an NPE is thrown due 
to how the Default Output Directory is calculated.

{code}
    public static final String DEFAULT_OUTPUT_DIRECTORY = "../" + 
Paths.get(".").toAbsolutePath().normalize().getFileName().toString();
{code}
