There 100% needs to be better unit testing for the PutEmail processor and I
agree that this ticket is outside the scope of that. I've created a new one
here[1]. Stubbing things out is a valid approach since the unit test can't
embed an smtp server. Feel free to comment there with more ideas!

> ArrayIndexOutOfBoundsException in PutEmail if property expansion fails for
> PutEmail.FROM
> ----------------------------------------------------------------------------------------
>
> Key: NIFI-1434
> URL: https://issues.apache.org/jira/browse/NIFI-1434
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 0.4.1
> Reporter: Richard Miskin
>
> If the FROM property in PutEmail evaluates to an empty string an
> ArrayIndexOutOfBoundsException is thrown from the following code:
> {code:java}
> message.setFrom(InternetAddress.parse(context.getProperty(FROM)
> .evaluateAttributeExpressions(flowFile).getValue())[0]);
> {code}
> This leads to the FlowFile not being transferred to the REL_FAILURE
> relationship and the exception propagates out of the onTrigger method.
