>                 URL: https://issues.apache.org/jira/browse/NIFI-4348
>             Project: Apache NiFi
>          Issue Type: Improvement
>          Components: Core Framework
>    Affects Versions: 1.3.0
>            Reporter: Kay-Uwe Moosheimer
>            Priority: Trivial
>
> The following code throws a NPE:
>     PropertyValue property = context.getProperty(SOME_PROPERTY);
>     if (property.isExpressionLanguagePresent()) {
> when the property is not set (NULL).
> So I have to write
>     PropertyValue property = context.getProperty(SOME_PROPERTY);
>     if (property.isSet() && property.isExpressionLanguagePresent()) {    
> It would be great if the method isExpressionLanguagePresent() checks for NULL and then return false.
